NAME
       TESTING/EIG/dget34.f

SYNOPSIS
   Functions/Subroutines
       subroutine dget34 (rmax, lmax, ninfo, knt)
           DGET34

Function/Subroutine Documentation
   subroutine dget34 (double precision rmax, integer lmax, integer, dimension(
       2 ) ninfo, integer knt)
       DGET34

       Purpose:


            DGET34 tests DLAEXC, a routine for swapping adjacent 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' * [ A B ] * Q  = [ C1 B1 ]
                     [ 0 C ]        [ 0  A1 ]

            where C1 is similar to C and A1 is similar to A.  Both A and C are
            assumed to be in standard form (equal diagonal entries and
            offdiagonal with differing signs) and A1 and C1 are returned with the
            same properties.

            The test code verifies these last assertions, as well as that
            the residual in the above equation is small.

       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 (2)
                     NINFO(J) is the number of examples where INFO=J occurred.

           KNT

                     KNT is INTEGER
                     Total number of examples tested.
