SPGL1: Spectral Projected Gradient for L1 minimization

This SPGL1 toolbox is a port to Scilab of the original SPGL1 Matlab toolbox developped by E. van den Berg & M. P. Friedlander and available at :

SPGL1 original toolbox

The Scilab port has been performed by F. Béreux, based on version v1.8 of the original SPGL1 toolbox and is released with the same license (GNU General Public License v2). It has been updated to v1.9 of the original SPGL1 toolbox (2015-05-17).
