Hi, Is there routines in Octave to do this? http://en.wikipedia.org/wiki/Non-negative_matrix_factorization
I got the hand on several packages that are distributed under "personal" licenses or no license at all. I have contacted the authors and waiting for answers. In case no answer comes, does anybody has an idea how to proceed? 1. http://www.cc.gatech.edu/~hpark/nmfsoftware.php 2. http://cogsys.imm.dtu.dk/toolbox/nmf/index.html (this last one includes the routine form this guy) 3. http://www.csie.ntu.edu.tw/~cjlin/nmf/ - The first one present this as license " The NMF:DTU Toolbox holds a collection of Non-negative Matrix Factorization (NMF) algorithms implemented for Matlab™.
