	Evaluates composite function f(g(theX)).

Detailed Description

template<typename Outer, typename Inner>
class MathUtils::Composite< Outer, Inner >

Composite functor: f(g(x)). Evaluates the outer function at the result of the inner function.

Usage:

Polynomial aInner({0.0, 1.0});         // g(x) = x
Polynomial aOuter({-1.0, 0.0, 1.0});   // f(x) = x^2 - 1
Composite aComp(aOuter, aInner);       // f(g(x)) = x^2 - 1

Template Parameters

Outer	outer function type (must have Value method)
Inner	inner function type (must have Value method)
