## 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.
