NAME
       TESTING/EIG/dget35.f

SYNOPSIS
   Functions/Subroutines
       subroutine dget35 (rmax, lmax, ninfo, knt)
           DGET35

Function/Subroutine Documentation
   subroutine dget35 (double precision rmax, integer lmax, integer ninfo,
       integer knt)
       DGET35

       Purpose:


            DGET35 tests DTRSYL, a routine for solving the Sylvester matrix
            equation

               op(A)*X + ISGN*X*op(B) = scale*C,

            A and B are assumed to be in Schur canonical form, op() represents an
            optional transpose, and ISGN can be -1 or +1.  Scale is an output
            less than or equal to 1, chosen to avoid overflow in X.

            The test code verifies that the following residual is order 1:

               norm(op(A)*X + ISGN*X*op(B) - scale*C) /
                   (EPS*max(norm(A),norm(B))*norm(X))

       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 where INFO is nonzero.

           KNT

                     KNT is INTEGER
                     Total number of examples tested.
