Detailed Description

template<int n, typename TRing, typename TOwner, typename TAlloc, typename TX>
class DGtal::MPolynomialEvaluatorImpl< n, TRing, TOwner, TAlloc, TX >::EvalFun2

Evaluates a polynomial of type poly<n, T> in myEvalPoint; the coefficients of the first indeterminate (which are polynomials of type poly<n-1, Ring>) are casted to poly<n-1, X>, and the result is of type poly<n-1, X> as well.

Evaluate: the first indeterminate is replaced by myEvalPoint, and the coefficients of the first indeterminate (which are polynomials of type poly<n-1, Ring>) are casted to the type poly<n-1, X>.
