NAME
       TESTING/EIG/cget35.f

SYNOPSIS
   Functions/Subroutines
       subroutine cget35 (rmax, lmax, ninfo, knt, nin)
           CGET35

Function/Subroutine Documentation
   subroutine cget35 (real rmax, integer lmax, integer ninfo, integer knt,
       integer nin)
       CGET35

       Purpose:


           !>
           !> CGET35 tests CTRSYL, 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 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 where INFO is nonzero.
           !>

           KNT

           !>          KNT is INTEGER
           !>          Total number of examples tested.
           !>

           NIN

           !>          NIN is INTEGER
           !>          Input logical unit number.
           !>
