10.4.4 A lower bound for the positive real roots of a polynomial
The poslbLMQ command uses
the Local Max Quadratic (LMQ) Akritas-Strzebonski-Vigklas algorithm to
find lower bounds for the positive real roots of polynomials.
poslbLMQ takes
P, a polynomial.
poslbLMQ(P) returns a
(non-optimal) lower bound for the positive real roots of P.
