Ok, one of the authors answred. Mail copied below " Dear Juan, Many thanks. Indeed my nmf code was released under free bsd licence, which is compatable to GPL: http://www.csie.ntu.edu.tw/~cjlin/nmf/COPYRIGHT So you are welcome to have it in octave-forge Best, Chih-Jen " I was thinking to add mnf.m to linear-algebra. Is that OK? -- M. Sc.
