'''MATLAB''' (navnet er dannet som en [[sammentrækning]] af de to matemtaiske begreber '''MAT'''''rix'' og '''LAB'''''oratory''<ref>[https://orbit.dtu.dk/en/publications/the-matlab-syntax-explore-the-syntax The Matlab Syntax: Explore the syntax — DTU Research Database<!-- Botgenereret titel -->]</ref>) er et [[matematik]]-[[computerprogram]] som fokuserer på anvendelsen af [[matrix|matricer]] og [[Vektor (matematik)|vektorer]].

== Opståen og features ==
Programmet så dagens lys sidst i [[1970]]'erne,<ref name="autogeneret1">[https://se.mathworks.com/company/aboutus/founders/clevemoler.html MathWorks - Founders - Cleve Moler - MATLAB & Simulink<!-- Botgenereret titel -->]</ref> og på daværende tidspunkt var [[Cleve Moler]]<ref name="autogeneret1" /> hovedophavsmanden bag dette program.
Foruden numeriske beregninger er det også muligt at lave grafer (plots) og grafiske bruger-interface.

'''Styresystemer'''

MATLAB findes til disse styresystemer:

[[Microsoft Windows|Windows]], [[Mac OS|macOS]] og [[Linux]]<ref>[https://www.mathworks.com/support/requirements/product-requirements-platform-availability-list.html#ML Add-On Product Requirements & Platform Availability - MATLAB & Simulink<!-- Botgenereret titel -->]</ref>

== Anvendelse i Danmark ==
MATLAB er et af [[ingeniører]]nes foretrukne [[matematik]]-[[computerprogram]]mer. I Danmark bliver MATLAB blandt andet anvendt på en række universiteter: [[Aalborg Universitet]],<ref>[https://first.math.aau.dk/dan/software/matlab/ Matematik på første studieår på Aalborg Universitet<!-- Botgenereret titel -->]</ref> [[Syddansk Universitet]], [[Danmarks Tekniske Universitet]],<ref>[http://www.gbar.dtu.dk/faq/28-matlab MATLAB<!-- Botgenereret titel -->]</ref> [[Ingeniørhøjskolen Aarhus Universitet]], [[Ingeniørhøjskolen i København]], [[Københavns Universitet]],<ref>{{Cite web |url=http://dk.elogin-db.com/punkt-ku-dk |title=Arkiveret kopi |access-date=20. december 2020 |archive-date=20. februar 2021 |archive-url=https://web.archive.org/web/20210220030744/http://dk.elogin-db.com/punkt-ku-dk |url-status=dead }}</ref> [[Roskilde Universitet]].<ref>http://quantumgravity.ruc.dk/MatLabNote/matlabnote.pdf</ref> Firmaet [[COWI]] anvender også MATLAB.

== Presseomtale ==
Disse tre CAS-softwares hjælper [[kunstig intelligens]] med at lære matematik: MATLAB, [[Maple]] og [[Mathematica]].<ref>{{Cite web |url=https://spainsnews.com/facebook-trains-an-artificial-intelligence-capable-of-solving-equations-innovation/ |title=Facebook trains an artificial intelligence capable of solving equations {{!}} Innovation {{!}} Spain's News<!-- Botgenereret titel --> |access-date=16. december 2020 |archive-date=27. oktober 2020 |archive-url=https://web.archive.org/web/20201027154627/https://spainsnews.com/facebook-trains-an-artificial-intelligence-capable-of-solving-equations-innovation/ |url-status=dead }}</ref>
