Detailed Description

Two points numerical derivative function wrapper.

Numerical derivatives use two points to compute the (first order) derivatives. $x_0$ is the focus point and $x_{+1} = x_0+h$ (or $x_0-h$ , if constrained on the right). Corresponding function values are $f_0$ , $f_{-1}$ and $f_{+1/-1}$ respectively. The derivatives are then computed using the central formulas:

$\begin{eqnarray*} \dfrac{\partial f}{\partial x } &=& \dfrac{f_{+1}-f_{0}}{h}\mathrm{\ or}\\ \dfrac{\partial f}{\partial x } &=& \dfrac{f_{0}-f_{-1}}{h}\\ \end{eqnarray*}$

This class does not allow computation of second order derivatives.

The $h$ parameter is computed in a parameter dependent manner: $h = x \times e$ , with $x \neq 0$ being the current parameter value. If $x = 0$ , $h = e$ . Default value is provided for $e$ and corresponds to the _h field. The default value works fine in most cases, but you may want to change it using the setInterval method.
