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).
