ZERRED tests the error exits for the eigenvalue driver routines for
 DOUBLE COMPLEX PRECISION matrices:
 PATH  driver   description

 ZEV   ZGEEV    find eigenvalues/eigenvectors for nonsymmetric A
 ZES   ZGEES    find eigenvalues/Schur form for nonsymmetric A
 ZVX   ZGEEVX   ZGEEV + balancing and condition estimation
 ZSX   ZGEESX   ZGEES + balancing and condition estimation
 ZBD   ZGESVD   compute SVD of an M-by-N matrix A
       ZGESDD   compute SVD of an M-by-N matrix A(by divide and
                conquer)
       ZGEJSV   compute SVD of an M-by-N matrix A where M >= N
       ZGESVDX  compute SVD of an M-by-N matrix A(by bisection
                and inverse iteration)
       ZGESVDQ  compute SVD of an M-by-N matrix A(with a 
                QR-Preconditioned )

PATH

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

NUNIT

          NUNIT is INTEGER
          The unit number for output.
