Detailed Description

template<int n, typename TRing, typename TOwner, typename TAlloc, typename TX>
template<typename XX, typename Fun>
class DGtal::MPolynomialEvaluatorImpl< n, TRing, TOwner, TAlloc, TX >::EvalFun< XX, Fun >

Evaluates a polynomial of type MPolynomial<n, TRing> in myEvalPoint; the coefficients of the first indeterminate are evaluated using the given functor of type Fun.

inline

Evaluate: the first indeterminate is replaced by myEvalPoint, and the coefficients of the first indeterminate (which are polynomials of type poly<n-1, T>) are evaluated using myEvalFun.
