SYNOPSIS
   Functions/Subroutines
       subroutine derred (path, nunit)
           DERRED

Function/Subroutine Documentation
   subroutine derred (character*3 path, integer nunit)
       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.
