NAME
       TESTING/EIG/zget36.f

SYNOPSIS
   Functions/Subroutines
       subroutine zget36 (rmax, lmax, ninfo, knt, nin)
           ZGET36

Function/Subroutine Documentation
   subroutine zget36 (double precision rmax, integer lmax, integer ninfo,
       integer knt, integer nin)
       ZGET36

       Purpose:


            ZGET36 tests ZTREXC, a routine for reordering diagonal entries of a
            matrix in complex Schur form. Thus, ZLAEXC computes a unitary matrix
            Q such that

               Q' * T1 * Q  = T2

            and where one of the diagonal blocks of T1 (the one at row IFST) has
            been moved to position ILST.

            The test code verifies that the residual Q'*T1*Q-T2 is small, that T2
            is in Schur form, and that the final position of the IFST block is
            ILST.

            The test matrices are read from a file with logical unit number NIN.

       Parameters
           RMAX

                     RMAX is DOUBLE PRECISION
                     Value of the largest test ratio.

           LMAX

                     LMAX is INTEGER
                     Example number where largest test ratio achieved.

           NINFO

                     NINFO is INTEGER
                     Number of examples where INFO is nonzero.

           KNT

                     KNT is INTEGER
                     Total number of examples tested.

           NIN

                     NIN is INTEGER
                     Input logical unit number.
