NAME
       TESTING/EIG/dget33.f

SYNOPSIS
   Functions/Subroutines
       subroutine dget33 (rmax, lmax, ninfo, knt)
           DGET33

Function/Subroutine Documentation
   subroutine dget33 (double precision rmax, integer lmax, integer ninfo,
       integer knt)
       DGET33

       Purpose:


            DGET33 tests DLANV2, a routine for putting 2 by 2 blocks into
            standard form.  In other words, it computes a two by two rotation
            [[C,S];[-S,C]] where in

               [ C S ][T(1,1) T(1,2)][ C -S ] = [ T11 T12 ]
               [-S C ][T(2,1) T(2,2)][ S  C ]   [ T21 T22 ]

            either
               1) T21=0 (real eigenvalues), or
               2) T11=T22 and T21*T12<0 (complex conjugate eigenvalues).
            We also  verify that the residual 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
                     Number of examples returned with INFO .NE. 0.

           KNT

                     KNT is INTEGER
                     Total number of examples tested.
