zget35()

subroutine zget35	(	double precision	RMAX,
		integer	LMAX,
		integer	NINFO,
		integer	KNT,
		integer	NIN
	)

ZGET35

Purpose:

 ZGET35 tests ZTRSYL, 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

[out]	RMAX	RMAX is DOUBLE PRECISION Value of the largest test ratio.
[out]	LMAX	LMAX is INTEGER Example number where largest test ratio achieved.
[out]	NINFO	NINFO is INTEGER Number of examples where INFO is nonzero.
[out]	KNT	KNT is INTEGER Total number of examples tested.
[in]	NIN	NIN is INTEGER Input logical unit number.
