template<class ParentFunctor, typename PointerToObj, typename PointerToMemFn, typename PointerToGradMemFn>
class ROOT::Math::MemGradFunHandler< ParentFunctor, PointerToObj, PointerToMemFn, PointerToGradMemFn >

Functor Handler to Wrap pointers to member functions for the evaluation of the function and the gradient.

The member function type must be (XXX means any name is allowed) : double XXX ( double x) for 1D function and derivative evaluation double XXX (const double *x) for multi-dimensional function evaluation and double XXX (cost double *x, int icoord) for partial derivatives evaluation
