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))

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.
