A one dimensional scaled polynomial class.

Prerequisite

Synopsis

A SPolynomial<T> contains a set of coefficients; its fundamental operations is evaluating itself at some "x". The number of coefficients is the order of the polynomial plus one, plus an additional 3 as height, center, width.

Example

 SPolynomial<Float> pf(3); // Third order polynomial - coeffs 0 by default
 pf.setCoefficient(1, 1.0);
 pf[5] = 2.0;
 pf.setCoefficient(3, 3.0);  // 3x^3 + 2x^2 + x
 pf(2); // == 34
