Function/Subroutine Documentation
subroutine sget35 (real rmax, integer lmax, integer ninfo, integer knt)
SGET35
Purpose:
SGET35 tests STRSYL, 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.
