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
    PATH

    !>          PATH is CHARACTER*3
    !>          The LAPACK path name for the routines to be tested.
    !>

    NUNIT

    !>          NUNIT is INTEGER
    !>          The unit number for output.
