'''MATLAB''' (
Although MATLAB is intended primarily for numeric computing, an optional toolbox uses the [[MuPAD]] [[computer algebra system|symbolic engine]] allowing access to [[symbolic computing]] abilities. An additional package, [[Simulink]], adds graphical multi-___domain simulation and [[model-based design]] for [[dynamical system|dynamic]] and [[embedded system]]s.

==History==
===Origins===
MATLAB was invented by mathematician and computer programmer [[Cleve Moler]].<ref name="Chonacky Winch 2005 pp. 9–10">{{cite journal | last1=Chonacky | first1=N. | last2=Winch | first2=D. | title=Reviews of Maple, Mathematica, and Matlab: Coming Soon to a Publication Near You | journal=Computing in Science & Engineering | publisher=Institute of Electrical and Electronics Engineers (IEEE) | volume=7 | issue=2 | year=2005 | issn=1521-9615 | doi=10.1109/mcse.2005.39 | pages=9–10| bibcode=2005CSE.....7b...9C | s2cid=29660034 }}</ref> The idea for MATLAB was based on his 1960s PhD [[thesis]].<ref name="Chonacky Winch 2005 pp. 9–10" /> Moler became a math professor at the [[University of New Mexico]] and started developing MATLAB for his students<ref name="Chonacky Winch 2005 pp. 9–10" /> as a hobby.<ref name="hobby" /> He developed MATLAB's initial [[linear algebra]] programming in 1967 with his one-time thesis advisor, [[George Forsythe]].<ref name="Chonacky Winch 2005 pp. 9–10" /> This was followed by [[Fortran]] code for [[Linear equation|linear equations]] in 1971.<ref name="Chonacky Winch 2005 pp. 9–10" />
Before version 1.0, MATLAB "was not a programming language; it was a simple interactive [[Matrix (mathematics)|matrix]] calculator. There were no programs, no toolboxes, no graphics. And no [[Ordinary differential equation|ODE]]s or [[FFT]]s."<ref>{{Cite web|title=A Brief History of MATLAB|url=https://www.mathworks.com/company/newsletters/articles/a-brief-history-of-matlab.html|access-date=2021-09-04|website=www.mathworks.com|language=en}}</ref>
The first early version of MATLAB was completed in the late 1970s.<ref name="Chonacky Winch 2005 pp. 9–10" /> The software was disclosed to the public for the first time in February 1979 at the [[Naval Postgraduate School]] in California.<ref name="hobby">{{cite journal|url=http://www.tomandmaria.com/Tom/Writing/MolerBio.pdf|first=Thomas|last=Haigh|title=Cleve Moler: Mathematical Software Pioneer and Creator of Matlab|publisher=IEEE Computer Society|journal=IEEE Annals of the History of Computing}}</ref> Early versions of MATLAB were simple [[Matrix (mathematics)|matrix calculators]] with 71 pre-built functions.<ref name="Moler Little pp. 1–67">{{cite journal | last1=Moler | first1=Cleve | last2=Little | first2=Jack | title=A history of MATLAB | journal=Proceedings of the ACM on Programming Languages | publisher=Association for Computing Machinery (ACM) | volume=4 | issue=HOPL | date=June 12, 2020 | pages=1–67 | issn=2475-1421 | doi=10.1145/3386331| doi-access=free }}</ref> At the time, MATLAB was distributed for free<ref name="Xue Press 2020 p. 21">{{cite book | last1=Xue | first1=D. | last2=Press | first2=T.U. | title=MATLAB Programming: Mathematical Problem Solutions | publisher=De Gruyter | series=De Gruyter STEM | year=2020 | isbn=978-3-11-066370-9 | url=https://books.google.com/books?id=0Y7ZDwAAQBAJ&pg=PP21 | access-date=September 16, 2020 | page=21}}</ref><ref name="Press 2008 p. 6">{{cite book | last=Press | first=CRC | title=Solving Applied Mathematical Problems with MATLAB | publisher=CRC Press | year=2008 | isbn=978-1-4200-8251-7 | url=https://books.google.com/books?id=V4vulPEc29kC&pg=PA6 | access-date=September 16, 2020 | page=6}}</ref> to universities.<ref name="Woodford Phillips 2011 p. 1">{{cite book | last1=Woodford | first1=C. | last2=Phillips | first2=C. | title=Numerical Methods with Worked Examples: Matlab Edition | publisher=Springer Netherlands | series=SpringerLink : Bücher | year=2011 | isbn=978-94-007-1366-6 | url=https://books.google.com/books?id=L90JVxIvA0YC&pg=PA1 | access-date=September 16, 2020 | page=1}}</ref> Moler would leave copies at universities he visited and the software developed a strong following in the math departments of university campuses.<ref name="Tranquillo 2011 p.">{{cite book | last=Tranquillo | first=J.V. | title=MATLAB for Engineering and the Life Sciences | publisher=Morgan & Claypool Publishers | series=Synthesis digital library of engineering and computer science | year=2011 | isbn=978-1-60845-710-6 | url=https://books.google.com/books?id=ofWpMryW0lgC | access-date=September 17, 2020 | page=}}</ref>{{RP|5}}
In the 1980s, Cleve Moler met [[John N. Little]]. They decided to reprogram MATLAB in [[C (programming language)|C]] and market it for the [[IBM]] [[Desktop computer|desktops]] that were replacing [[Mainframe computer|mainframe computers]] at the time.<ref name="Chonacky Winch 2005 pp. 9–10" /> John Little and programmer Steve Bangert re-programmed MATLAB in C, created the MATLAB programming language, and developed features for toolboxes.<ref name="hobby" />

==Syntax==
The MATLAB application is built around the MATLAB programming language.
Common usage of the MATLAB application involves using the "[[Command-line interface|Command Window]]" as an interactive mathematical [[command line interface|shell]] or executing [[Text file|text files]] containing MATLAB code.<ref>{{cite web|url=http://www.mathworks.com/help/matlab/index.html|title=MATLAB Documentation === "Hello, world!" example ===
Line 105 ⟶ 371:
===Variables===
[[Variable (computer science)|Variables]] are defined using the [[Assignment (computer science)|assignment]] operator, <code>=</code>.
MATLAB is a [[Strong and weak typing|weakly typed]] programming language because [[Data type|types]] are implicitly converted.<ref>{{cite web|title=Comparing MATLAB with Other OO Languages|url=http://www.mathworks.com/help/matlab/matlab_oop/matlab-vs-other-oo-languages.html|work=MATLAB|publisher=MathWorks|access-date=August 14, 2013|archive-date=October 29, 2013|archive-url=https://web.archive.org/web/20131029194449/http://www.mathworks.com/help/matlab/matlab_oop/matlab-vs-other-oo-languages.html|url-status=dead}}</ref> It is an [[Type inference|inferred]] [[Type system|typed language]] because variables can be assigned without declaring their type, except if they are to be treated as symbolic objects,<ref>{{cite web|title=Create Symbolic Variables and Expressions|url=http://www.mathworks.com/help/symbolic/creating-symbolic-variables-and-expressions.html|work=Symbolic Math Toolbox|publisher=MathWorks|access-date=August 14, 2013|archive-date=July 12, 2013|archive-url=https://web.archive.org/web/20130712032649/http://www.mathworks.com/help/symbolic/creating-symbolic-variables-and-expressions.html|url-status=dead}}</ref> and that their type can change.
Values can come from [[constant (computer science)|constant]]s, from computation involving values of other variables, or from the output of a [[Function (computer programming)|function]].
For example:
<syntaxhighlight lang="matlabsession">
>> x = 17
Line 141 ⟶ 413:
assigns to the variable named <code>ari</code> an array with the values 1, 2, 3, 4, and 5, since the default value of 1 is used as the increment.
[[One-based indexing|Indexing]] is one-based,<ref>{{cite web|title=Matrix Indexing|url=http://www.mathworks.com/help/matlab/math/matrix-indexing.html|publisher=MathWorks|access-date=August 14, 2013|archive-date=August 9, 2018|archive-url=https://web.archive.org/web/20180809011619/http://www.mathworks.com/help/matlab/math/matrix-indexing.html|url-status=dead}}</ref> which is the usual convention for [[matrix (mathematics)|matrices]] in mathematics, unlike zero-based indexing commonly used in other programming languages such as C, [[C++]], and [[Java (programming language)|Java]].
Matrices can be defined by separating the elements of a row with blank space or comma and using a semicolon to separate the rows. The list of elements should be surrounded by square brackets <code>[]</code>. Parentheses <code>()</code> are used to access elements and subarrays (they are also used to denote a function argument list).
Line 215 ⟶ 487:
=== Structures ===
MATLAB supports structure data types.<ref>{{cite web|title=Structures|url=http://www.mathworks.com/help/matlab/structures.html|publisher=MathWorks|access-date=August 14, 2013|archive-date=July 13, 2019|archive-url=https://web.archive.org/web/20190713130421/https://www.mathworks.com/help/matlab/structures.html|url-status=dead}}</ref> 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<ref>{{cite web|title=Generate Field Names from Variables|url=http://www.mathworks.com/help/matlab/matlab_prog/generate-field-names-from-variables.html|publisher=MathWorks|access-date=August 14, 2013|archive-date=December 5, 2019|archive-url=https://web.archive.org/web/20191205162532/https://www.mathworks.com/help/matlab/matlab_prog/generate-field-names-from-variables.html|url-status=dead}}</ref> (field look-ups by name, field manipulations, etc.).
=== Functions ===
Line 238 ⟶ 510:
=== Function handles ===
MATLAB supports elements of [[lambda calculus]] by introducing function handles,<ref>{{cite web|title=Function Handles|url=http://www.mathworks.com/help/matlab/function-handles.html|publisher=MathWorks|access-date=August 14, 2013|archive-date=July 19, 2020|archive-url=https://web.archive.org/web/20200719160702/https://www.mathworks.com/help/matlab/function-handles.html|url-status=dead}}</ref> or function references, which are implemented either in .m files or anonymous<ref>{{cite web|title=Anonymous Functions|url=http://www.mathworks.com/help/matlab/matlab_prog/anonymous-functions.html|publisher=MathWorks|access-date=August 14, 2013}}{{Dead link|date=July 2025 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>/nested functions.<ref>{{cite web|title=Nested Functions|url=http://www.mathworks.com/help/matlab/matlab_prog/nested-functions.html|publisher=MathWorks.|access-date=August 14, 2013|archive-date=July 19, 2020|archive-url=https://web.archive.org/web/20200719221302/https://www.mathworks.com/help/matlab/matlab_prog/nested-functions.html|url-status=dead}}</ref>
=== Classes and object-oriented programming ===
MATLAB supports [[object-oriented programming]] including classes, [[inheritance (object-oriented programming)|inheritance]], virtual dispatch, packages, [[pass-by-value]] semantics, and [[pass-by-reference]] semantics.<ref>{{cite web|url=http://www.mathworks.com/help/matlab/object-oriented-programming.html
Method call behavior is different between value and reference classes. For example, a call to a method:
