class ROOT::Math::Functor1D: public ROOT::Math::IBaseFunctionOneDim

   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:
   <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)
   The function dimension is required when constructing the functor.
