template<class ParentFunctor>
class ROOT::Math::FunctorGradHandler< ParentFunctor >

Functor Handler class for gradient functions where both callable objects are provided for the function evaluation (type Func) and for the gradient (type GradFunc) .

It can be created from any function implementing the correct signature corresponding to the requested type The function evaluation (Func) In the case of multi-dimension the function evaluation object must implement double operator() (const double * x) and the gradient function object must implement double operator() (const double * x, int icoord)
