its very good

15 Feb 2012 predictor-corrector algorithm Solves linear least squares with nonnegative variables Author: Uriel Roque Becker, Stephen

For a matrix with 600 rows and 500 columns, this function was quite slow. I would recommend another method. The 'active set' and 'block pivot' methods by the same author are both much faster. Those codes are:

good

I experienced the same bug as the first comment.
