Purpose
DERRED tests the error exits for the eigenvalue driver routines for
DOUBLE PRECISION matrices:
PATH driver description
SEV DGEEV find eigenvalues/eigenvectors for nonsymmetric A
SES DGEES find eigenvalues/Schur form for nonsymmetric A
SVX DGEEVX SGEEV + balancing and condition estimation
SSX DGEESX SGEES + balancing and condition estimation
DBD DGESVD compute SVD of an M-by-N matrix A
DGESDD compute SVD of an M-by-N matrix A (by divide and
conquer)
