However, while they are often provided and uploaded by users under an Octave compatible and proper open source BSD license, the fileexchange's Terms of use prohibit any usage beside MathWorks' proprietary MATLAB. There are a few purposeful, albeit minor, syntax additions: Many of the numerous MATLAB functions are available in GNU
