CGET35
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))
[out] | RMAX | RMAX is REAL 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. |
