	In some cases, the derivative algorithm will use information from the previous step, these can be passed in with this overload.
T	Derivative (const T *x, unsigned int icoord=0) const
	Return the partial derivative with respect to the passed coordinate.
virtual void	FdF (const T *x, T &f, T *df) const
	Optimized method to evaluate at the same time the function value and derivative at a point x.
virtual void	Gradient (const T *x, T *grad) const
	Evaluate all the vector of function derivatives (gradient) at a point x.
virtual bool	HasGradient () const
T	operator() (const T *x) const
