Documentation for class Functor class. It is used to wrap in a very simple and convenient way multi-dimensional function objects. It can wrap all the following types: <ul> <li> any C++ callable object implemention double operator()( const double * ) <li> a free C function of type double ()(double * ) <li> a member function with the correct signature like Foo::Eval(const double * ). In this case one pass the object pointer and a pointer to the member function (&Foo::Eval) </ul> The function dimension is required when constructing the functor. @ingroup GenFunc

construct from a callable object of multi-dimension
implementing operator()(const double *x) and
Derivative(const double * x,icoord)
{}
construct from a pointer to member function and member function types for function and derivative evaluations
{}
construct for Gradient Functions of multi-dimension
Func gives the function evaluatiion, GradFunc the partial derivatives
The function dimension is required
