Max , also known as Max/MSP/Jitter , is a visual programming language for music and multimedia developed and maintained by San Francisco -based software company Cycling '74 . Over its more than thirty-year history, it has been used by composers, performers, software designers, researchers, and artists to create recordings, performances, and installations.
84-438: The Max program is modular, with most routines existing as shared libraries . An application programming interface (API) allows third-party development of new routines (named external objects ). Thus, Max has a large user base of programmers unaffiliated with Cycling '74 who enhance the software with commercial and non-commercial extensions to the program. Because of this extensible design, which simultaneously represents both

336-401: A i , j ) 1 ≤ i , j ≤ n {\displaystyle \mathbf {A} =(a_{i,j})_{1\leq i,j\leq n}} in the case that n = m {\displaystyle n=m} . Matrices are usually symbolized using upper-case letters (such as A {\displaystyle {\mathbf {A} }} in the examples above), while
420-672: A field or a ring . In this section, it is supposed that matrix entries belong to a fixed ring, which is typically a field of numbers. The sum A + B of two m × n matrices A and B is calculated entrywise: ( A + B ) i , j = A i , j + B i , j , 1 ≤ i ≤ m , 1 ≤ j ≤ n . {\displaystyle ({\mathbf {A}}+{\mathbf {B}})_{i,j}={\mathbf {A}}_{i,j}+{\mathbf {B}}_{i,j},\quad 1\leq i\leq m,\quad 1\leq j\leq n.} For example, The product c A of
504-700: A k -by- m matrix B represents another linear map g : R m → R k {\displaystyle g:\mathbb {R} ^{m}\to \mathbb {R} ^{k}} , then the composition g ∘ f is represented by BA since ( g ∘ f ) ( x ) = g ( f ( x ) ) = g ( A x ) = B ( A x ) = ( B A ) x . {\displaystyle (g\circ f)({\mathbf {x}})=g(f({\mathbf {x}}))=g({\mathbf {Ax}})={\mathbf {B}}({\mathbf {Ax}})=({\mathbf {BA}}){\mathbf {x}}.} The last equality follows from
588-467: A matrix ( pl. : matrices ) is a rectangular array or table of numbers , symbols , or expressions , with elements or entries arranged in rows and columns, which is used to represent a mathematical object or property of such an object. For example, [ 1 9 − 13 20 5 − 6 ] {\displaystyle {\begin{bmatrix}1&9&-13\\20&5&-6\end{bmatrix}}}
672-458: A run-time linker API . For instance, Microsoft Windows uses the API functions LoadLibrary , LoadLibraryEx , FreeLibrary and GetProcAddress with Microsoft Dynamic Link Libraries ; POSIX -based systems, including most UNIX and UNIX-like systems, use dlopen , dlclose and dlsym . Some development systems automate this process. Matrix (mathematics) In mathematics ,

The parallelogram pictured at the right is obtained by multiplying A with each of the column vectors [ 0 0 ] , [ 1 0 ] , [ 1 1 ] {\displaystyle {\begin{bmatrix}0\\0\end{bmatrix}},{\begin{bmatrix}1\\0\end{bmatrix}},{\begin{bmatrix}1\\1\end{bmatrix}}} , and [ 0 1 ] {\displaystyle {\begin{bmatrix}0\\1\end{bmatrix}}} in turn. These vectors define
840-406: A 2-by-3 submatrix by removing row 3 and column 2: The minors and cofactors of a matrix are found by computing the determinant of certain submatrices. A principal submatrix is a square submatrix obtained by removing certain rows and columns. The definition varies from author to author. According to some authors, a principal submatrix is a submatrix in which the set of row indices that remain
924-828: A general-purpose computer like the Macintosh PowerBook G3 . In 1999, the Netochka Nezvanova collective released NATO.0+55+3d , a suite of externals that added extensive real-time video control to Max. Though NATO.0+55+3d became increasingly popular among multimedia artists, its development stopped abruptly in 2001. SoftVNS , another set of extensions for visual processing in Max, was released in 2002 by Canadian media artist David Rokeby . Cycling '74 released their own set of video extensions, Jitter , alongside Max 4 in 2003, adding real-time video, OpenGL graphics, and matrix processing capabilities. Max 4

#17327762402431008-412: A likely load address for each shared library on the system before it is needed and store that information in the libraries and executables. If every shared library that is loaded has undergone this process, then each will load at its predetermined address, which speeds up the process of dynamic linking. This optimization is known as prebinding or prelinking on macOS and Linux, respectively. IBM z/VM uses
1092-407: A matrix are called rows and columns , respectively. The size of a matrix is defined by the number of rows and columns it contains. There is no limit to the number of rows and columns, that a matrix (in the usual sense) can have as long as they are positive integers. A matrix with m {\displaystyle {m}} rows and n {\displaystyle {n}} columns
1176-429: A matrix over a field F is a rectangular array of elements of F . A real matrix and a complex matrix are matrices whose entries are respectively real numbers or complex numbers . More general types of entries are discussed below . For instance, this is a real matrix: The numbers, symbols, or expressions in the matrix are called its entries or its elements . The horizontal and vertical lines of entries in
1260-412: A matrix plus the rank equals the number of columns of the matrix. A square matrix is a matrix with the same number of rows and columns. An n -by- n matrix is known as a square matrix of order n . Any two square matrices of the same order can be added and multiplied. The entries a ii form the main diagonal of a square matrix. They lie on the imaginary line that runs from the top left corner to
1344-596: A nonzero determinant and the eigenvalues of a square matrix are the roots of a polynomial determinant. In geometry , matrices are widely used for specifying and representing geometric transformations (for example rotations ) and coordinate changes . In numerical analysis , many computational problems are solved by reducing them to a matrix computation, and this often involves computing with matrices of huge dimensions. Matrices are used in most areas of mathematics and scientific fields, either directly, or through their use in geometry and numerical analysis. Matrix theory
1428-464: A number c (also called a scalar in this context) and a matrix A is computed by multiplying every entry of A by c : ( c A ) i , j = c ⋅ A i , j {\displaystyle (c{\mathbf {A}})_{i,j}=c\cdot {\mathbf {A}}_{i,j}} This operation is called scalar multiplication , but its result is not named "scalar product" to avoid confusion, since "scalar product"
1512-580: A piano and controlled a Sogitec 4X for audio processing. In 1989, IRCAM developed Max/FTS ("Faster Than Sound"), a version of Max ported to the IRCAM Signal Processing Workstation (ISPW) for the NeXT . Also known as "Audio Max", it would prove a forerunner to Max's MSP audio extensions, adding the ability to do real-time synthesis using an internal hardware digital signal processor (DSP) board. The same year, IRCAM licensed
1596-571: A shared library that an executable depends on is deleted, moved, or renamed, or if an incompatible version of the library is copied to a place that is earlier in the search, the executable would fail to load. This is called dependency hell , existing on many platforms. The (infamous) Windows variant is commonly known as DLL hell . This problem cannot occur if each version of each library is uniquely identified and each program references libraries only by their full unique identifiers. The "DLL hell" problems with earlier Windows versions arose from using only
1680-409: A similar technique, called "Discontinuous Saved Segments" (DCSS). Disadvantages of this technique include the time required to precompute these addresses every time the shared libraries change, the inability to use address space layout randomization , and the requirement of sufficient virtual address space for use (a problem that will be alleviated by the adoption of 64-bit architectures, at least for

#17327762402431848-743: A subscript. For instance, the matrix A {\displaystyle \mathbf {A} } above is 3 × 4 {\displaystyle 3\times 4} , and can be defined as A = [ i − j ] ( i = 1 , 2 , 3 ; j = 1 , … , 4 ) {\displaystyle {\mathbf {A} }=[i-j](i=1,2,3;j=1,\dots ,4)} or A = [ i − j ] 3 × 4 {\displaystyle {\mathbf {A} }=[i-j]_{3\times 4}} . Some programming languages utilize doubly subscripted arrays (or arrays of arrays) to represent an m -by- n matrix. Some programming languages start
1932-509: A subset of dynamic linking, involves a dynamically linked library loading and unloading at runtime on request. Such a request may be made implicitly or explicitly. Implicit requests are made when a compiler or static linker adds library references that include file paths or simply file names. Explicit requests are made when applications make direct calls to an operating system's API. Most operating systems that support dynamically linked libraries also support dynamically loading such libraries via
2016-478: A time cost when first starting the system. Most Unix-like systems have a "search path" specifying file-system directories in which to look for dynamic libraries. Some systems specify the default path in a configuration file , others hard-code it into the dynamic loader. Some executable file formats can specify additional directories in which to search for libraries for a particular program. This can usually be overridden with an environment variable , although it
2100-399: Is commutative , that is, the matrix sum does not depend on the order of the summands: A + B = B + A . The transpose is compatible with addition and scalar multiplication, as expressed by ( c A ) = c ( A ) and ( A + B ) = A + B . Finally, ( A ) = A . Multiplication of two matrices is defined if and only if the number of columns of the left matrix is the same as
2184-446: Is a 3 × 2 {\displaystyle {3\times 2}} matrix. Matrices with a single row are called row vectors , and those with a single column are called column vectors . A matrix with the same number of rows and columns is called a square matrix . A matrix with an infinite number of rows or columns (or both) is called an infinite matrix . In some contexts, such as computer algebra programs , it
2268-428: Is a computer file that contains executable code designed to be used by multiple computer programs or other libraries at runtime . When running a program that is configured to use a shared library, the operating system loads the shared library from a file (other than the program's executable file) into memory at load time or runtime . For perspective, a program can alternatively be monolithic—built to include
2352-619: Is a matrix with two rows and three columns. This is often referred to as a "two-by-three matrix", a " 2 × 3 {\displaystyle 2\times 3} matrix", or a matrix of dimension 2 × 3 {\displaystyle 2\times 3} . Matrices are commonly related to linear algebra . Notable exceptions include incidence matrices and adjacency matrices in graph theory . This article focuses on matrices related to linear algebra, and, unless otherwise specified, all matrices represent linear maps or may be viewed as such. Square matrices , matrices with
2436-470: Is an m × n matrix, x designates a column vector (that is, n ×1 -matrix) of n variables x 1 , x 2 , ..., x n , and b is an m ×1 -column vector, then the matrix equation is equivalent to the system of linear equations Using matrices, this can be solved more compactly than would be possible by writing out all the equations separately. If n = m and the equations are independent , then this can be done by writing where A
2520-407: Is being loaded ( load time ) or executed ( runtime ), rather than when the executable file is created. A dynamically linked library ( dynamic-link library , or DLL, under Windows and OS/2 ; shareable image under OpenVMS ; dynamic shared object, or DSO, under Unix-like systems) is a library intended for dynamic linking. Only a minimal amount of work is done by the linker when the executable file
2604-456: Is called an m × n {\displaystyle {m\times n}} matrix, or m {\displaystyle {m}} -by- n {\displaystyle {n}} matrix, where m {\displaystyle {m}} and n {\displaystyle {n}} are called its dimensions . For example, the matrix A {\displaystyle {\mathbf {A} }} above

2688-410: Is created; it only records what library routines the program needs and the index names or numbers of the routines in the library. The majority of the work of linking is done at the time the application is loaded (load time) or during execution (runtime). Usually, the necessary linking program, called a dynamic linker or linking loader , is actually part of the underlying operating system . (However, it
2772-457: Is disabled for setuid and setgid programs, so that a user can't force such a program to run arbitrary code with root permissions. Developers of libraries are encouraged to place their dynamic libraries in places in the default search path. On the downside, this can make installation of new libraries problematic, and these "known" locations quickly become home to an increasing number of library files, making management more complex. Dynamic loading,
2856-472: Is not commutative , in marked contrast to (rational, real, or complex) numbers, whose product is independent of the order of the factors. An example of two matrices not commuting with each other is: whereas Besides the ordinary matrix multiplication just described, other less frequently used operations on matrices that can be considered forms of multiplication also exist, such as the Hadamard product and
2940-668: Is often denoted M ( m , n ) , {\displaystyle {\mathcal {M}}(m,n),} or M m × n ( R ) . {\displaystyle {\mathcal {M}}_{m\times n}(\mathbb {R} ).} The set of all m -by- n matrices over another field , or over a ring R , is similarly denoted M ( m , n , R ) , {\displaystyle {\mathcal {M}}(m,n,R),} or M m × n ( R ) . {\displaystyle {\mathcal {M}}_{m\times n}(R).} If m = n , such as in
3024-666: Is often used as a synonym for " inner product ". For example: The subtraction of two m × n matrices is defined by composing matrix addition with scalar multiplication by –1 : The transpose of an m × n matrix A is the n × m matrix A (also denoted A or A ) formed by turning rows into columns and vice versa: ( A T ) i , j = A j , i . {\displaystyle \left({\mathbf {A}}^{\rm {T}}\right)_{i,j}={\mathbf {A}}_{j,i}.} For example: Familiar properties of numbers extend to these operations on matrices: for example, addition
3108-565: Is possible, and not exceedingly difficult, to write a program that uses dynamic linking and includes its own dynamic linker, even for an operating system that itself provides no support for dynamic linking.) Programmers originally developed dynamic linking in the Multics operating system, starting in 1964, and the MTS ( Michigan Terminal System ), built in the late 1960s. Since shared libraries on most systems do not change often, systems can compute
3192-447: Is the branch of mathematics that focuses on the study of matrices. It was initially a sub-branch of linear algebra , but soon grew to include subjects related to graph theory , algebra , combinatorics and statistics . A matrix is a rectangular array of numbers (or other mathematical objects), called the entries of the matrix. Matrices are subject to standard operations such as addition and multiplication . Most commonly,
3276-418: Is the i th coordinate of f ( e j ) , where e j = (0, ..., 0, 1, 0, ..., 0) is the unit vector with 1 in the j th position and 0 elsewhere. The matrix A is said to represent the linear map f , and A is called the transformation matrix of f . For example, the 2×2 matrix can be viewed as the transform of the unit square into a parallelogram with vertices at (0, 0) , (
3360-590: Is the inverse matrix of A . If A has no inverse, solutions—if any—can be found using its generalized inverse . Matrices and matrix multiplication reveal their essential features when related to linear transformations , also known as linear maps . A real m -by- n matrix A gives rise to a linear transformation R n → R m {\displaystyle \mathbb {R} ^{n}\to \mathbb {R} ^{m}} mapping each vector x in R n {\displaystyle \mathbb {R} ^{n}} to
3444-413: Is the same as the set of column indices that remain. Other authors define a principal submatrix as one in which the first k rows and columns, for some number k , are the ones that remain; this type of submatrix has also been called a leading principal submatrix . Matrices can be used to compactly write and work with multiple linear equations, that is, systems of linear equations. For example, if A

3528-447: Is used in place of M . {\displaystyle {\mathcal {M}}.} Several basic operations can be applied to matrices. Some, such as transposition and submatrix do not depend on the nature of the entries. Others, such as matrix addition , scalar multiplication , matrix multiplication , and row operations involve operations on matrix entries and therefore require that matrix entries are numbers or belong to
3612-442: Is useful to consider a matrix with no rows or no columns, called an empty matrix . The specifics of symbolic matrix notation vary widely, with some prevailing trends. Matrices are commonly written in square brackets or parentheses , so that an m × n {\displaystyle m\times n} matrix A {\displaystyle \mathbf {A} } is represented as A = [
3696-550: The ( 1 , 3 ) {\displaystyle (1,3)} entry of the following matrix A {\displaystyle \mathbf {A} } is 5 (also denoted a 13 {\displaystyle {a_{13}}} , a 1 , 3 {\displaystyle {a_{1,3}}} , A [ 1 , 3 ] {\displaystyle \mathbf {A} [1,3]} or A 1 , 3 {\displaystyle {{\mathbf {A} }_{1,3}}} ): Sometimes,

Library code may be shared in memory by multiple processes , and on disk. If virtual memory is used, processes would execute the same physical page of RAM that is mapped into the different address spaces of the processes. This has advantages. For instance, on
3864-533: The Kronecker product . They arise in solving matrix equations such as the Sylvester equation . There are three types of row operations: These operations are used in several ways, including solving linear equations and finding matrix inverses . A submatrix of a matrix is a matrix obtained by deleting any collection of rows and/or columns. For example, from the following 3-by-4 matrix, we can construct
3948-455: The Macintosh . At this point in its development Max couldn't perform its own real-time sound synthesis in software, but instead sent control messages to external hardware synthesizers and samplers using MIDI or a similar protocol . Its earliest widely recognized use in composition was for Pluton , a 1988 piano and computer piece by Philippe Manoury ; the software synchronized a computer to
4032-644: The OpenStep system, applications were often only a few hundred kilobytes in size and loaded quickly; most of their code was located in libraries that had already been loaded for other purposes by the operating system. Programs can accomplish RAM sharing by using position-independent code , as in Unix , which leads to a complex but flexible architecture, or by using common virtual addresses, as in Windows and OS/2 . These systems ensure, by various means, like pre-mapping
4116-1050: The n -by- n matrix in which all the elements on the main diagonal are equal to 1 and all other elements are equal to 0, for example, I 1 = [ 1 ] , I 2 = [ 1 0 0 1 ] , ⋮ I n = [ 1 0 ⋯ 0 0 1 ⋯ 0 ⋮ ⋮ ⋱ ⋮ 0 0 ⋯ 1 ] {\displaystyle {\begin{aligned}\mathbf {I} _{1}&={\begin{bmatrix}1\end{bmatrix}},\\[4pt]\mathbf {I} _{2}&={\begin{bmatrix}1&0\\0&1\end{bmatrix}},\\[4pt]\vdots &\\[4pt]\mathbf {I} _{n}&={\begin{bmatrix}1&0&\cdots &0\\0&1&\cdots &0\\\vdots &\vdots &\ddots &\vdots \\0&0&\cdots &1\end{bmatrix}}\end{aligned}}} It
4200-557: The program 's structure and its graphical user interface (GUI), Max has been described as the lingua franca for developing interactive music performance software. Miller Puckette began work on Max in 1985, at the Institut de Recherche et Coordination Acoustique/Musique (IRCAM) in Paris . Originally called The Patcher , this first version provided composers with a graphical interface for creating interactive computer music scores on

4452-794: The DSP (this corresponds to the distinction between k-rate and a-rate processes in Csound , and control rate vs. audio rate in SuperCollider ). The basic language of Max and its sibling programs is that of a data-flow system: Max programs (named patches ) are made by arranging and connecting building-blocks of objects within a patcher , or visual canvas. These objects act as self-contained programs (in reality, they are dynamically linked libraries), each of which may receive input (through one or more visual inlets ), generate output (through visual outlets ), or both. Objects pass messages from their outlets to
4536-564: The IRCAM versions, continued in the same tradition. Cycling '74's first Max release, in 1997, was derived partly from Puckette's work on Pure Data. Called Max/MSP ("Max Signal Processing", or the initials Miller Smith Puckette), it remains the most notable of Max's many extensions and incarnations: it made Max capable of manipulating real-time digital audio signals without dedicated DSP hardware. This meant that composers could now create their own complex synthesizers and effects processors using only
4620-734: The Jitter package adds a scalable, multi-dimensional data structure for handling large sets of numbers for storing video and other datasets ( matrix data). Max is typically learned through acquiring a vocabulary of objects and how they function within a patcher; for example, the metro object functions as a simple metronome, and the random object generates random integers. Most objects are non-graphical, consisting only of an object's name and several arguments-attributes (in essence class properties) typed into an object box . Other objects are graphical, including sliders, number boxes, dials, table editors, pull-down menus, buttons, and other objects for running
4704-483: The Max for Live extension. With the increased integration of laptop computers into live music performance (in electronic music and elsewhere), Max/MSP and Max/Jitter have received attention as a development environment available to those serious about laptop music/video performance. Programs sharing Max's visual programming concepts are now commonly used for real-time audio and video synthesis and processing. Shared library A shared library or shared object
4788-409: The above-mentioned associativity of matrix multiplication. The rank of a matrix A is the maximum number of linearly independent row vectors of the matrix, which is the same as the maximum number of linearly independent column vectors. Equivalently it is the dimension of the image of the linear map represented by A . The rank–nullity theorem states that the dimension of the kernel of

A third alternative is single-level store , as used by the IBM System/38 and its successors. This allows position-dependent code, but places no significant restrictions on where code can be placed or how it can be shared. In some cases, different versions of shared libraries can cause problems, especially when libraries of different versions have

Similarly, if all entries of A above the main diagonal are zero, A is called a lower triangular matrix . If all entries outside the main diagonal are zero, A is called a diagonal matrix . The identity matrix I n of size n is

Some of the new features include MC, a new way to work with multiple channels, JavaScript support with Node for Max, and Vizzie 2. On October 29, 2024 Max 9 was released. Max is named after composer Max Mathews , and can be considered a descendant of his MUSIC language, though its graphical nature disguises that fact. Like most MUSIC-N languages, Max distinguishes between two levels of time: that of an event scheduler, and that of
5292-503: The corresponding lower-case letters, with two subscript indices (e.g., a 11 {\displaystyle {a_{11}}} , or a 1 , 1 {\displaystyle {a_{1,1}}} ), represent the entries. In addition to using upper-case letters to symbolize matrices, many authors use a special typographical style , commonly boldface Roman (non-italic), to further distinguish matrices from other mathematical objects. An alternative notation involves

Applications written for the .NET Framework (since 2002), also check the Global Assembly Cache as the primary store of shared dll files to remove the issue of DLL hell . OpenStep used a more flexible system, collecting a list of libraries from a number of known locations (similar to the PATH concept) when the system first starts. Moving libraries around causes no problems at all, although users incur
5460-442: The entries of a matrix can be defined by a formula such as a i , j = f ( i , j ) {\displaystyle a_{i,j}=f(i,j)} . For example, each of the entries of the following matrix A {\displaystyle \mathbf {A} } is determined by the formula a i j = i − j {\displaystyle a_{ij}=i-j} . In this case,
5544-452: The executable code of the library in its executable file, but the library code embedded in the program's executable file is not usable by other programs. Shared libraries can be statically linked at compile-time, meaning that references to the library are resolved and the library is allocated memory when the executable file is created. But often linking of shared libraries is postponed until they are loaded. Most modern operating systems use
5628-553: The graph of objects is defined by the visual organization of the objects in the patcher itself. As a result of this organizing principle, Max is unusual in that the program logic and the interface as presented to the user are typically related, though newer versions of Max provide several technologies for more standard GUI design. Max documents (named patchers) can be bundled into stand-alone applications and distributed free or sold commercially. In addition, Max can be used to author audio and MIDI plugin software for Ableton Live through
5712-519: The inlets of connected objects. Max supports six basic atomic data types that can be transmitted as messages from object to object: int, float, list, symbol, bang, and signal (for MSP audio connections). Several more complex data structures exist within the program for handling numeric arrays ( table data), hash tables ( coll data), XML information ( pattr data), and JSON-based dictionaries ( dict data). An MSP data structure ( buffer~ ) can hold digital audio information within program memory. In addition,
5796-474: The matrix itself is sometimes defined by that formula, within square brackets or double parentheses. For example, the matrix above is defined as A = [ i − j ] {\displaystyle {\mathbf {A} }=[i-j]} or A = ( ( i − j ) ) {\displaystyle {\mathbf {A} }=((i-j))} . If matrix size is m × n {\displaystyle m\times n} ,

5964-413: The names of libraries, which were not guaranteed to be unique, to resolve dynamic links in programs. (To avoid "DLL hell", later versions of Windows rely largely on options for programs to install private DLLs—essentially a partial retreat from the use of shared libraries—along with mechanisms to prevent replacement of shared system DLLs with earlier versions of them.) Microsoft Windows checks
6048-474: The number of rows of the right matrix. If A is an m × n matrix and B is an n × p matrix, then their matrix product AB is the m × p matrix whose entries are given by dot product of the corresponding row of A and the corresponding column of B : where 1 ≤ i ≤ m and 1 ≤ j ≤ p . For example, the underlined entry 2340 in the product is calculated as (2 × 1000) + (3 × 100) + (4 × 10) = 2340: Matrix multiplication satisfies
6132-497: The numbering of array indexes at zero, in which case the entries of an m -by- n matrix are indexed by 0 ≤ i ≤ m − 1 {\displaystyle 0\leq i\leq m-1} and 0 ≤ j ≤ n − 1 {\displaystyle 0\leq j\leq n-1} . This article follows the more common convention in mathematical writing where enumeration starts from 1 . The set of all m -by- n real matrices
6216-416: The program interactively. Max/MSP/Jitter comes with about 600 of these objects as the standard package; extensions to the program can be written by third-party developers as Max patchers (e.g. by encapsulating some of the functionality of a patcher into a sub-program that is itself a Max patch), or as objects written in C , C++ , Java , or JavaScript . The order of execution for messages traversing through
6300-651: The rules ( AB ) C = A ( BC ) ( associativity ), and ( A + B ) C = AC + BC as well as C ( A + B ) = CA + CB (left and right distributivity ), whenever the size of the matrices is such that the various products are defined. The product AB may be defined without BA being defined, namely if A and B are m × n and n × k matrices, respectively, and m ≠ k . Even if both products are defined, they generally need not be equal, that is: A B ≠ B A . {\displaystyle {\mathbf {AB}}\neq {\mathbf {BA}}.} In other words, matrix multiplication
6384-401: The same file name, and different applications installed on a system each require a specific version. Such a scenario is known as DLL hell , named after the Windows and OS/2 DLL file . Most modern operating systems after 2001 have clean-up methods to eliminate such situations or use application-specific "private" libraries. Dynamic linking or late binding is linking performed while a program
6468-501: The same format for both shared libraries and executable files. This offers two main advantages: first, it requires only one loader (building and maintaining a single loader is considered well worth any added complexity). Secondly, it allows an executable file to be used as a shared library (if it has a symbol table ). Examples of file formats use for both shared libraries and executable files include ELF , Mach-O , and PE . In some older environments such as 16-bit Windows or MPE for
6552-405: The same number of rows and columns, play a major role in matrix theory. Square matrices of a given dimension form a noncommutative ring , which is one of the most common examples of a noncommutative ring. The determinant of a square matrix is a number associated with the matrix, which is fundamental for the study of a square matrix; for example, a square matrix is invertible if and only if it has
6636-461: The software to Opcode Systems . Opcode launched a commercial version named Max in 1990, developed and extended by David Zicarelli . However, by 1997, Opcode was considering cancelling it. Instead, Zicarelli acquired the publishing rights and founded a new company, Cycling '74, to continue commercial development. The timing was fortunate, as Opcode was acquired by Gibson Guitar in 1998 and ended operations in 1999. IRCAM's in-house Max development
6720-440: The time being). Loaders for shared libraries vary widely in functionality. Some depend on the executable storing explicit paths to the libraries. Any change to the library naming or layout of the file system will cause these systems to fail. More commonly, only the name of the library (and not the path) is stored in the executable, with the operating system supplying a method to find the library on disk, based on some algorithm. If
6804-458: The use of a double-underline with the variable name, with or without boldface style, as in A _ _ {\displaystyle {\underline {\underline {A}}}} . The entry in the i -th row and j -th column of a matrix A is sometimes referred to as the i , j {\displaystyle {i,j}} or ( i , j ) {\displaystyle {(i,j)}} entry of
6888-467: The vertices of the unit square. The following table shows several 2×2 real matrices with the associated linear maps of R 2 . {\displaystyle \mathbb {R} ^{2}.} The blue original is mapped to the green grid and shapes. The origin (0, 0) is marked with a black point. Under the 1-to-1 correspondence between matrices and linear maps, matrix multiplication corresponds to composition of maps: if
6972-600: Was also the first version to run on Windows . Max 5, released in 2008, redesigned the patching GUI for the first time in Max's commercial history. In 2011, Max 6 added a new audio engine compatible with 64-bit operating systems, integration with Ableton Live sequencer software, and an extension called Gen, which can compile optimized Max patches for higher performance. Max 7 was released in 2014 and focused on 3D rendering improvements. On June 6, 2017, Ableton announced its purchase of Cycling '74, with Max continuing to be published by Cycling '74 and David Zicarelli remaining with
7056-495: Was also winding down; the last version produced there was jMax , a direct descendant of Max/FTS developed in 1998 for Silicon Graphics (SGI) and later for Linux systems. It used Java for its graphical interface and C for its real-time backend, and was eventually released as open-source software . Meanwhile, Puckette had independently released a fully redesigned open-source composition tool named Pure Data (Pd) in 1996, which, despite some underlying engineering differences from
