mm::RBFWeight< RBFType, vec_t > Class Template Reference

#include <WeightFunction_fwd.hpp>

Detailed Description

template<class RBFType, class vec_t>
class mm::RBFWeight< RBFType, vec_t >

Represents a weight function constructed from a Radial Basis function.

Template Parameters

RBFType	Type of the RBF used. Must satisfy the Radial Basis Function concept.
vec_t	Vector type used in calculations.

The weight function \(w\) is defined as \(w(x) = f(\|x\|_2^2)\), where \(f\) is the given radial basis function.

This class satisfies the Weight function concept.

Usage example:

    double s = 1.23;
    RBFWeight<Gaussian<double>, Vec2d> weight(s);
    Vec2d p(1.37, -0.97);
    double val = weight(p);
    std::cout << weight << std::endl;
