Does anyone have any good suggestions for a solver of sparse *underdetermined* linear equations? I don't need the entire solution space; any old solution will do. I have about 1400 equations in about 2800 unknowns. Right now, I'm using a slight modification of the Numerical Recipes SPARSE() routine, but the results are quite poor (that is, it returns an unacceptably large RSQ).
