It tests if all roots lie in the left half of the complex plane B=hup(C) is the same as B=all(real(roots(c))<0) but much faster. The Algorithm is based on the Routh-Scheme. C are the elements of the Polynomial C(1)*X^N + ... + C(N)*X + C(N+1). HUP2 works also for multiple polynomials, each row a poly - Yet not tested REFERENCES: F.
