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

Template Type Argument Requirements (T)

• T should have standard numerical operators. Current implementation only tested for real types (and their AutoDiffs).

Thrown Exceptions

• Assertion in debug mode if attempt is made to address incorrect coefficients

To Do

• Nothing I know of
