tpsv Interface

public interface tpsv

TPSV solves one of the systems of equations Ax = b, or ATx = b, or A*Hx = b, where b and x are n element vectors and A is an n by n unit, or non-unit, upper or lower triangular matrix, supplied in packed form. No test for singularity or near-singularity is included in this routine. Such tests must be performed before calling this routine.
