A proprietary programming language developed by Math. Works, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, C#, Java, Fortran and Python. Although MATLAB is intended primarily for numerical computing, an optional toolbox uses the Mu. PADsymbolic engine, allowing access to symbolic computing abilities. An additional package, Simulink, adds graphical multi- domain simulation and model- based design for dynamic and embedded systems. As of 2. 01. 7, MATLAB has over 2 million users across industry and academia.[7] MATLAB users come from various backgrounds of engineering, science, and economics. History[edit]Cleve Moler, the chairman of the computer science department at the University of New Mexico, started developing MATLAB in the late 1. He designed it to give his students access to LINPACK and EISPACK without them having to learn Fortran. It soon spread to other universities and found a strong audience within the applied mathematics community. Jack Little, an engineer, was exposed to it during a visit Moler made to Stanford University in 1. Recognizing its commercial potential, he joined with Moler and Steve Bangert. They rewrote MATLAB in C and founded Math. Works in 1. 98. 4 to continue its development. These rewritten libraries were known as JACKPAC.[9] In 2. MATLAB was rewritten to use a newer set of libraries for matrix manipulation, LAPACK.[1. MATLAB was first adopted by researchers and practitioners in control engineering, Little's specialty, but quickly spread to many other domains. It is now also used in education, in particular the teaching of linear algebra, numerical analysis, and is popular amongst scientists involved in image processing.[8]The MATLAB application is built around the MATLAB scripting language. Common usage of the MATLAB application involves using the Command Window as an interactive mathematical shell or executing text files containing MATLAB code.[1. Variables[edit]Variables are defined using the assignment operator, =. MATLAB is a weakly typed programming language because types are implicitly converted.[1. It is an inferred typed language because variables can be assigned without declaring their type, except if they are to be treated as symbolic objects,[1. Values can come from constants, from computation involving values of other variables, or from the output of a function. For example: > > x=1. Vectors and matrices[edit]A simple array is defined using the colon syntax: init: increment: terminator. For instance: defines a variable named array (or assigns a new value to an existing variable with the name array) which is an array consisting of the values 1, 3, 5, 7, and 9. That is, the array starts at 1 (the init value), increments with each step from the previous value by 2 (the increment value), and stops once it reaches (or to avoid exceeding) 9 (the terminator value). Indexing is one- based,[1. C, C++, and Java. Matrices can be defined by separating the elements of a row with blank space or comma and using a semicolon to terminate each row. The list of elements should be surrounded by square brackets: []. Parentheses: () are used to access elements and subarrays (they are also used to denote a function argument list).> > A=[1. A=1. 63. 21. 35. 10. A(2,3)ans=1. 1Sets of indices can be specified by expressions such as "2: 4", which evaluates to [2, 3, 4]. For example, a submatrix taken from rows 2 through 4 and columns 3 through 4 can be written as: > > A(2: 4,3: 4)ans=1. A square identity matrix of size n can be generated using the function eye, and matrices of any size with zeros or ones can be generated with the functions zeros and ones, respectively.> > eye(3,3)ans=1. Transposing a vector or a matrix is done either by the function transpose or by adding prime to the matrix.> > A=[1; 2],B=A',C=transpose(A)A=1. B=1. 2C=1. 2> > D=[0. D'D=0. 31. 5ans=0. Most MATLAB functions can accept matrices and will apply themselves to each element. For example, mod(2*J,n) will multiply every element in "J" by 2, and then reduce each element modulo "n". MATLAB does include standard "for" and "while" loops, but (as in other similar applications such as R), using the vectorized notation often produces code that is faster to execute. This code, excerpted from the function magic. M for odd values of n (MATLAB function meshgrid is used here to generate square matrices I and J containing 1: n).[J,I]=meshgrid(1: n); A=mod(I+J- (n+3)/2,n); B=mod(I+2*J- 2,n); M=n*A+B+1; Structures[edit]MATLAB has structure data types.[1. Since all variables in MATLAB are arrays, a more adequate name is "structure array", where each element of the array has the same field names. In addition, MATLAB supports dynamic field names[1. Unfortunately, MATLAB JIT does not support MATLAB structures, therefore just a simple bundling of various variables into a structure will come at a cost.[1. Functions[edit]When creating a MATLAB function, the name of the file should match the name of the first function in the file. Valid function names begin with an alphabetic character, and can contain letters, numbers, or underscores. Functions are also often case sensitive. Function handles[edit]MATLAB supports elements of lambda calculus by introducing function handles,[1. Classes and object- oriented programming[edit]MATLAB supports object- oriented programming including classes, inheritance, virtual dispatch, packages, pass- by- value semantics, and pass- by- reference semantics.[2. However, the syntax and calling conventions are significantly different from other languages. MATLAB has value classes and reference classes, depending on whether the class has handle as a super- class (for reference classes) or not (for value classes).[2. Method call behavior is different between value and reference classes. For example, a call to a methodcan alter any member of object only if object is an instance of a reference class. An example of a simple class is provided below. Hello!')endendend. When put into a file named hello. Hello! Graphics and graphical user interface programming[edit]MATLAB supports developing applications with graphical user interface (GUI) features. MATLAB includes GUIDE[2. GUI development environment) for graphically designing GUIs.[2. It also has tightly integrated graph- plotting features. For example, the function plot can be used to produce a graph from two vectors x and y. The code: x=0: pi/1. A MATLAB program can produce three- dimensional graphics using the functions surf, plot. In MATLAB, graphical user interfaces can be programmed with the GUI design environment (GUIDE) tool.[2. Interfacing with other languages[edit]MATLAB can call functions and subroutines written in the programming languages C or Fortran.[2. A wrapper function is created allowing MATLAB data types to be passed and returned. The dynamically loadable object files created by compiling such functions are termed "MEX- files" (for MATLAB executable).[2. Since 2. 01. 4 increasing two- way interfacing with Python is being added.[2. Libraries written in Perl, Java, Active. X or . NET can be directly called from MATLAB,[3. MATLAB libraries (for example XML or SQL support) are implemented as wrappers around Java or Active. X libraries. Calling MATLAB from Java is more complicated, but can be done with a MATLAB toolbox[3. Math. Works, or using an undocumented mechanism called JMI (Java- to- MATLAB Interface),[3. Java Metadata Interface that is also called JMI). Official MATLAB API for Java was added in 2. As alternatives to the Mu. PAD based Symbolic Math Toolbox available from Math. Works, MATLAB can be connected to Maple or Mathematica.[3. Libraries also exist to import and export Math. ML.[3. 9]License[edit]MATLAB is a proprietary product of Math. Works, so users are subject to vendor lock- in.[7][4. Although MATLAB Builder products can deploy MATLAB functions as library files which can be used with . NET[4. 1] or Java[4. MATLAB language. Each toolbox is purchased separately. If an evaluation license is requested, the Math. Works sales department requires detailed information about the project for which MATLAB is to be evaluated. If granted (which it often is), the evaluation license is valid for two to four weeks.
