class ROOT::Math::GradFunctor: public ROOT::Math::IGradientFunctionMultiDim

 LM 7/2/2014:  no needed this : make template ctor of Functor1D and GradFunctor1D not
 available to CINT s

#if defined(__MAKECINT__) || defined(G__DICTIONARY)
 needed since CINT initialize it with TRootIOCtor
class TRootIOCtor;

Function documentation

BaseFunc * Clone() const

 clone of the function handler (use copy-ctor)

unsigned int NDim() const

 constructor for multi-dimensional functions

double DoEval(const double* x) const

double DoDerivative(double x)

GradFunctor()

      Default constructor

{}

GradFunctor( const Func & f, unsigned int dim )

      construct from a callable object of multi-dimension
      implementing operator()(const double *x) and
      Derivative(const double * x,icoord)

{}

GradFunctor(const PtrObj& p, MemFn memFn, GradMemFn gradFn, unsigned int dim )

       construct from a pointer to member function and member function types for function and derivative evaluations

{}

GradFunctor(void* p1, void* p2, unsigned int dim)

      construct for Gradient Functions of multi-dimension
      Func gives the function evaluatiion, GradFunc the partial derivatives
      The function dimension is  required

{ }

virtual ~GradFunctor()

      Destructor (no operations)

{}
