LAPACK  3.6.1 LAPACK: Linear Algebra PACKage
 subroutine zerred ( character*3 PATH, integer NUNIT )

ZERRED

Purpose:
``` 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)```
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.```
