Synopsis

An EvenPolynomial<T> contains a set of coefficients; its fundamental operation is evaluating itself at some "x". The number of coefficients is the order of the polynomial divided by two, plus one, so is the number of available parameters.

Example

EvenPolynomial<Float> pf(3); // Second order polynomial - coeffs 0 by default
pf.setCoefficient(0, 1.0);
pf[1] = 2.0; // 2x^2 + 1x^0
pf(2); // == 8
