Sturm's theorem expresses the number of distinct real roots of p located in an interval in terms of the number of changes of signs of the values of the Sturm sequence …
What Is Rote Counting? (And How To Teach It)
WebIf a is a root of f, f = (x − a)q where q has degree n − 1. Since f(b) = 0 if and only if a = b or q(b) = 0, it follows by our inductive assumption that f has at most n roots.

WebTherefore, when roots in an interval are required, our method performs far better. The library is also capable of efficiently counting the number of roots inside an interval, of which RPOLY is incapable. For 8-order polynomials, our roots counter only takes about 0.2 microsecond under Intel i7-8700 CPU and 0.8 microsecond under Intel i5-5200U CPU. raymond james reviews 2020
