subroutine, public | cp_fm_diag::cp_fm_syevd (matrix, eigenvectors, eigenvalues, info) |
| Computes all eigenvalues and vectors of a real symmetric matrix significantly faster than syevx, scales also much better. Needs workspace to allocate all the eigenvectors. More...

subroutine, public | cp_fm_diag::cp_fm_syevx (matrix, eigenvectors, eigenvalues, neig, work_syevx) |
| compute eigenvalues and optionally eigenvectors of a real symmetric matrix using scalapack. If eigenvectors are required this routine will replicate a full matrix on each CPU... if more than a handful of vectors are needed, use cp_fm_syevd instead More...
