OSNOVNI UKAZI PROGRAMSKEGA JEZIKA MATLAB

Matlab ima zelo dobro dokumentacijo, ki je v celoti dostopna na Webu. Lahko jo tudi prenesete na svoj racunalnik v obliki PDF datotek.

• Osnovna stran na internetu je: http://www.mathworks.com/
• Za zacetnike je najprimernejša stran: http://www.mathworks.com/access/helpdesk/help/techdoc/basics/getstarted.shtml
• Za ukaze, ki so združeni v skupine (kot spodaj) je primerna stran: http://www.mathworks.com/access/helpdesk/help/techdoc/refbycat/groups.shtml
