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
