NAME
       TESTING/EIG/dget36.f

SYNOPSIS
   Functions/Subroutines
       subroutine dget36 (rmax, lmax, ninfo, knt, nin)
           DGET36

Function/Subroutine Documentation
   subroutine dget36 (double precision rmax, integer lmax, integer, dimension(
       3 ) ninfo, integer knt, integer nin)
       DGET36

       Purpose:


            DGET36 tests DTREXC, a routine for moving blocks (either 1 by 1 or
            2 by 2) on the diagonal of a matrix in real Schur form.  Thus, DLAEXC
            computes an orthogonal 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 (within +-1).

            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 array, dimension (3)
                     NINFO(J) is the number of examples where INFO=J.

           KNT

                     KNT is INTEGER
                     Total number of examples tested.

           NIN

                     NIN is INTEGER
                     Input logical unit number.
