◆ cerrtsqr()

subroutine cerrtsqr ( character*3  PATH,
integer  NUNIT 
)

CERRTSQR

Purpose:
 CERRTSQR tests the error exits for the COMPLEX routines
 that use the TSQR decomposition of a general matrix.
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.
