NAME
       TESTING/EIG/sget34.f

SYNOPSIS
   Functions/Subroutines
       subroutine sget34 (rmax, lmax, ninfo, knt)
           SGET34

Function/Subroutine Documentation
   subroutine sget34 (real rmax, integer lmax, integer, dimension( 2 ) ninfo,
       integer knt)
       SGET34

       Purpose:


            SGET34 tests SLAEXC, 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, SLAEXC 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 last assertions, as well as that
            the residual in the above equation is small.

       Parameters
           RMAX

                     RMAX is REAL
                     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.
