NAME
       TESTING/EIG/sget32.f

SYNOPSIS
   Functions/Subroutines
       subroutine sget32 (rmax, lmax, ninfo, knt)
           SGET32

Function/Subroutine Documentation
   subroutine sget32 (real rmax, integer lmax, integer ninfo, integer knt)
       SGET32

       Purpose:


            SGET32 tests SLASY2, a routine for solving

                    op(TL)*X + ISGN*X*op(TR) = SCALE*B

            where TL is N1 by N1, TR is N2 by N2, and N1,N2 =1 or 2 only.
            X and B are N1 by N2, op() is an optional transpose, an
            ISGN = 1 or -1. SCALE is chosen less than or equal to 1 to
            avoid overflow in X.

            The test condition is that the scaled residual

            norm( op(TL)*X + ISGN*X*op(TR) = SCALE*B )
                 / ( max( ulp*norm(TL), ulp*norm(TR)) * norm(X), SMLNUM )

            should be on the order of 1. Here, ulp is the machine precision.
            Also, it is verified that SCALE is less than or equal to 1, and
            that XNORM = infinity-norm(X).

       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
                     Number of examples returned with INFO.NE.0.

           KNT

                     KNT is INTEGER
                     Total number of examples tested.
