Hello,

I am interested in first 100 eigenvalues of a laplacian matrix (arising from 3D triangulated surface to
extract Morse-Simplices). Although I have googled a lot, I couldn't get any good package to this job.
Lapack and Scalapack work for dense matrices and give full spectrum, Arpack++ is buggy and not
compiled with modern compilers.

Any suggestion for robust and reliable modules which is capable of extracting few minimum eigenvalues
from a laplacian matrix will be a great help.

Thanks.
