TRRFS: provides error bounds and backward error estimates for the solution to a system of linear equations with a triangular coefficient matrix. The solution matrix X must be computed by CTRTRS or some other means before entering this routine. TRRFS does not do iterative refinement because doing so cannot improve the backward error.
