Detailed Description

template<int n, typename TRing, typename TAlloc, typename TX>
class DGtal::MPolynomialEvaluator< n, TRing, TAlloc, TX >

The top level polynomial evaluation class, in case n > 1, i.e. in case the coefficients are polynomials by themselves.

This class is a backport from Spielwiese.

Will be called by "child". Evaluates the polynomial into an element of XX (which must not necessarily be X, it can also be MPolynomial<k, X> for some k < n - 1) using the given functor to evaluate the coefficients, which are of type MPolynomial<n-1, Ring>.
