Questions about the numerical programming language MATLAB.
MATLAB (MATrix LABoratory) is a commercial software (MathWorks; originally developed at the University of New Mexico) that offers a high-level programming language with particular emphasis on vector and matrix based operations and plotting capabilities in an interactive development environment.
Questions tagged matlab should be concerned with the mathematical capabilities of Matlab (e.g., solving linear systems, using
eigs with anonymous functions, choosing functions or toolboxes for a certain scientific problem).
Questions about the programming language of MATLAB (e.g., vectorizing loops, manipulating arrays) belong to Stack Overflow; questions about the development environment (including manipulating plots) should be posted at MATLAB Central.
