MATLAB (an abbreviation of "MATrix LABoratory") is a proprietary multiparadigm programming language and numeric computing environment developed by MathWorks. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages.
Although MATLAB is intended primarily for numeric computing, an optional toolbox uses the MuPAD symbolic engine allowing access to symbolic computing abilities. An additional package, Simulink, adds graphical multidomain simulation and modelbased design for dynamic and embedded systems.
As of 2020, MATLAB has more than 4 million users worldwide.^{[21]} They come from various backgrounds of engineering, science, and economics.
History
Origins
MATLAB was invented by mathematician and computer programmer Cleve Moler.^{[22]} The idea for MATLAB was based on his 1960s PhD thesis.^{[22]} Moler became a math professor at the University of New Mexico and started developing MATLAB for his students^{[22]} as a hobby.^{[23]} He developed MATLAB's initial linear algebra programming in 1967 with his onetime thesis advisor, George Forsythe.^{[22]} This was followed by Fortran code for linear equations in 1971.^{[22]}
In the beginning (before version 1.0) MATLAB "was not a programming language; it was a simple interactive matrix calculator. There were no programs, no toolboxes, no graphics. And no ODEs or FFTs."^{[24]}
The first early version of MATLAB was completed in the late 1970s.^{[22]} The software was disclosed to the public for the first time in February 1979 at the Naval Postgraduate School in California.^{[23]} Early versions of MATLAB were simple matrix calculators with 71 prebuilt functions.^{[25]} At the time, MATLAB was distributed for free^{[26]}^{[27]} to universities.^{[28]} Moler would leave copies at universities he visited and the software developed a strong following in the math departments of university campuses.^{[29]}^{:5}
In the 1980s, Cleve Moler met John N. Little. They decided to reprogram MATLAB in C and market it for the IBM desktops that were replacing mainframe computers at the time.^{[22]} John Little and programmer Steve Bangert reprogrammed MATLAB in C, created the MATLAB programming language, and developed features for toolboxes.^{[23]}
Commercial development
MATLAB was first released as a commercial product in 1984 at the Automatic Control Conference in Las Vegas.^{[22]}^{[23]} MathWorks, Inc. was founded to develop the software^{[27]} and the MATLAB programming language was released.^{[25]} The first MATLAB sale was the following year, when Nick Trefethen from the Massachusetts Institute of Technology bought ten copies.^{[23]}^{[30]}
By the end of the 1980s, several hundred copies of MATLAB had been sold to universities for student use.^{[23]} The software was popularized largely thanks to toolboxes created by experts in various fields for performing specialized mathematical tasks.^{[26]} Many of the toolboxes were developed as a result of Stanford students that used MATLAB in academia, then brought the software with them to the private sector.^{[23]}
Over time, MATLAB was rewritten for early operating systems created by Digital Equipment Corporation, VAX, Sun Microsystems, and for Unix PCs.^{[23]}^{[25]} Version 3 was released in 1987.^{[31]} The first MATLAB compiler was developed by Stephen C. Johnson in the 1990s.^{[25]}
In 2000, MathWorks added a Fortranbased library for linear algebra in MATLAB 6, replacing the software's original LINPACK and EISPACK subroutines that were in C.^{[25]} MATLAB's Parallel Computing Toolbox was released at the 2004 Supercomputing Conference and support for graphics processing units (GPUs) was added to it in 2010.^{[25]}
Recent history
Some especially large changes to the software were made with version 8 in 2012.^{[32]} The user interface was reworked and Simulink's functionality was expanded.^{[33]} By 2016, MATLAB had introduced several technical and user interface improvements, including the MATLAB Live Editor notebook, and other features.^{[25]}
Features
MATLAB combines a desktop environment tuned for iterative analysis and design processes with a programming language that expresses matrix and array mathematics directly. It includes the Live Editor for creating scripts that combine code, output, and formatted text in an executable notebook. It allows to extend its functions and developments of all kinds of discipline through a set of characteristics called toolbox.

Syntax
The MATLAB application is built around the MATLAB programming language. Common usage of the MATLAB application involves using the "Command Window" as an interactive mathematical shell or executing text files containing MATLAB code.^{[35]}
Variables
Variables are defined using the assignment operator, =
. MATLAB is a weakly typed programming language because types are implicitly converted.^{[36]} 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,^{[37]} and that their type can change. Values can come from constants, from computation involving values of other variables, or from the output of a function. For example:
>> x = 17 x = 17 >> x = 'hat' x = hat >> x = [3*4, pi/2] x = 12.0000 1.5708 >> y = 3*sin(x) y = 1.6097 3.0000
Vectors and matrices
A simple array is defined using the colon syntax: initial:
increment:
terminator. For instance:
>> array = 1:2:9 array = 1 3 5 7 9
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 initial value), increments with each step from the previous value by 2 (the increment value), and stops once it reaches (or is about to exceed) 9 (the terminator value).
The increment value can actually be left out of this syntax (along with one of the colons), to use a default value of 1.
>> ari = 1:5 ari = 1 2 3 4 5
assigns to the variable named ari
an array with the values 1, 2, 3, 4, and 5, since the default value of 1 is used as the increment.
Indexing is onebased,^{[38]} which is the usual convention for matrices in mathematics, unlike zerobased indexing commonly used in other programming languages such as 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 = [16, 3, 2, 13 ; 5, 10, 11, 8; 9, 6, 7, 12 ; 4, 15, 14, 1] A = 16 3 2 13 5 10 11 8 9 6 7 12 4 15 14 1 >> A(2,3) ans = 11
Sets 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 = 11 8 7 12 14 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 0 0 0 1 0 0 0 1 >> zeros(2,3) ans = 0 0 0 0 0 0 >> ones(2,3) ans = 1 1 1 1 1 1
Transposing a vector or a matrix is done either by the function transpose
or by adding dotprime after the matrix (without the dot, prime will perform conjugate transpose for complex arrays):
>> A = [1 ; 2], B = A.', C = transpose(A) A = 1 2 B = 1 2 C = 1 2 >> D = [0, 3 ; 1, 5], D.' D = 0 3 1 5 ans = 0 1 3 5
Most functions accept arrays as input and operate elementwise on 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 is encouraged and is often faster to execute. The following code, excerpted from the function magic.m, creates a magic square 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
MATLAB supports structure data types.^{[39]} 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^{[40]} (field lookups by name, field manipulations, etc.).
Functions
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. Variables and functions are case sensitive.^{[41]} gbImage = imread('ecg.png'); grayImage = rgb2gray(rgbImage); % for nonindexed images level = graythresh(grayImage); % threshold for converting image to binary, binaryImage = im2bw(grayImage, level); % Extract the individual red, green, and blue color channels. redChannel = rgbImage(:, :, 1); greenChannel = rgbImage(:, :, 2); blueChannel = rgbImage(:, :, 3); % Make the black parts pure red. redChannel(~binaryImage) = 255; greenChannel(~binaryImage) = 0; blueChannel(~binaryImage) = 0; % Now recombine to form the output image. rgbImageOut = cat(3, redChannel, greenChannel, blueChannel); imshow(rgbImageOut);
Function handles
MATLAB supports elements of lambda calculus by introducing function handles,^{[42]} or function references, which are implemented either in .m files or anonymous^{[43]}/nested functions.^{[44]}
Classes and objectoriented programming
MATLAB supports objectoriented programming including classes, inheritance, virtual dispatch, packages, passbyvalue semantics, and passbyreference semantics.^{[45]} 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 superclass (for reference classes) or not (for value classes).^{[46]}
Method call behavior is different between value and reference classes. For example, a call to a method:
object.method();
can alter any member of object only if object is an instance of a reference class, otherwise value class methods must return a new instance if it needs to modify the object.
An example of a simple class is provided below:
classdef Hello methods function greet(obj) disp('Hello!') end end end
When put into a file named hello.m
, this can be executed with the following commands:
>> x = Hello(); >> x.greet(); Hello!
Graphics and graphical user interface programming
<graph>{ "version": 2, "width": 400, "height": 200, "data": [ { "name": "table", "values": [ { "x": 3, "y": 1 }, { "x": 1, "y": 3 }, { "x": 2, "y": 2 }, { "x": 3, "y": 4 } ] } ], "scales": [ { "name": "x", "type": "ordinal", "range": "width", "zero": false, "domain": { "data": "table", "field": "x" } }, { "name": "y", "type": "linear", "range": "height", "nice": true, "domain": { "data": "table", "field": "y" } } ], "axes": [ { "type": "x", "scale": "x" }, { "type": "y", "scale": "y" } ], "marks": [ { "type": "rect", "from": { "data": "table" }, "properties": { "enter": { "x": { "scale": "x", "field": "x" }, "y": { "scale": "y", "field": "y" }, "y2": { "scale": "y", "value": 0 }, "fill": { "value": "steelblue" }, "width": { "scale": "x", "band": "true", "offset": 1 } } } } ] }</graph>
MATLAB has tightly integrated graphplotting features. For example, the function plot can be used to produce a graph from two vectors x and y. The code:
x = 0:pi/100:2*pi; y = sin(x); plot(x,y)
produces the following figure of the sine function:
MATLAB supports threedimensional graphics as well:
[X,Y] = meshgrid(10:0.25:10,10:0.25:10); f = sinc(sqrt((X/pi).^2+(Y/pi).^2)); mesh(X,Y,f); axis([10 10 10 10 0.3 1]) xlabel('{\bfx}') ylabel('{\bfy}') zlabel('{\bfsinc} ({\bfR})') hidden off 
[X,Y] = meshgrid(10:0.25:10,10:0.25:10); f = sinc(sqrt((X/pi).^2+(Y/pi).^2)); surf(X,Y,f); axis([10 10 10 10 0.3 1]) xlabel('{\bfx}') ylabel('{\bfy}') zlabel('{\bfsinc} ({\bfR})')  
This code produces a wireframe 3D plot of the twodimensional unnormalized sinc function:  This code produces a surface 3D plot of the twodimensional unnormalized sinc function:  
MATLAB supports developing graphical user interface (GUI) applications.^{[47]} UIs can be generated either programmatically or using visual design environments such as GUIDE and App Designer.^{[48]}^{[49]}
MATLAB and other languages
MATLAB can call functions and subroutines written in the programming languages C or Fortran.^{[50]} A wrapper function is created allowing MATLAB data types to be passed and returned. MEX files (MATLAB executables) are the dynamically loadable object files created by compiling such functions.^{[51]}^{[52]} Since 2014 increasing twoway interfacing with Python was being added.^{[53]}^{[54]}
Libraries written in Perl, Java, ActiveX or .NET can be directly called from MATLAB,^{[55]}^{[56]} and many MATLAB libraries (for example XML or SQL support) are implemented as wrappers around Java or ActiveX libraries. Calling MATLAB from Java is more complicated, but can be done with a MATLAB toolbox^{[57]} which is sold separately by MathWorks, or using an undocumented mechanism called JMI (JavatoMATLAB Interface),^{[58]}^{[59]} (which should not be confused with the unrelated Java Metadata Interface that is also called JMI). Official MATLAB API for Java was added in 2016.^{[60]}
As alternatives to the MuPAD based Symbolic Math Toolbox available from MathWorks, MATLAB can be connected to Maple or Mathematica.^{[61]}^{[62]}
Libraries also exist to import and export MathML.^{[63]}
While MATLAB is the most popular commercial numerical computation software package,^{[64]} other alternatives are available, such as the open source computation language GNU Octave, the statistics programming language R, the computing environment Maple and the computational language Julia.^{[64]}^{[65]}
Withdrawal from China
In 2020, Chinese state media reported that MATLAB had withdrawn services from two Chinese universities as a result of US sanctions, and said this will be responded to by increased use of opensource alternatives and by developing domestic alternatives.^{[66]}
Release history
MATLAB is updated twice per year.^{[67]}^{:517}^{[33]} In addition to new features and other improvements, each release has new bug fixes and smaller changes.^{[68]}
