RE: NNLS function

Hmmm...I did't see anything in the octave-forge index that will do this.

I almost hate to point this out, but there appears to be a function you
could use that is freely downloadable from the Mathworks site:

http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=338
8&objectType=file

However, I'm not sure if that's legal, since the comments say: "Adapted from
NNLS of Mathworks, Inc.". (Unless you own Matlab?)

That said, it is an optimized version of the algorithm which is supposedly
faster and more flexible than the one in MATLAB.

If it's not buried somewhere in octave already, the "right thing" is
probably for someone to do a clean reimplementation of this, based only on
the 2 references cited in the included readme.txt file.

Thanks,
-Frank
