T	Derivative (const T x, unsigned int icoord, T previous_grad, T previous_g2, T previous_gstep) const
	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.
