DERRED

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)
       DGEJSV   compute SVD of an M-by-N matrix A where M >= N
       DGESVDX  compute SVD of an M-by-N matrix A(by bisection
                and inverse iteration)
       DGESVDQ  compute SVD of an M-by-N matrix A(with a 
                QR-Preconditioned )
Parameters
[in]PATH
          PATH is CHARACTER*3
          The LAPACK path name for the routines to be tested.
[in]NUNIT
          NUNIT is INTEGER
          The unit number for output.
