Detailed Description

Three points numerical derivative function wrapper.

Numerical derivatives use three points to compute the derivatives. $x_0$ is the focus point, $x_{-1} = x_0-h$ and $x_{+1} = x_0+h$ are other points, with function values $f_0$, $f_{-1}$ and $f_{+1}$ respectively. The derivatives are then computed using the central formulas:

\begin{eqnarray*} \dfrac{\partial f}{\partial x } &=& \dfrac{f_{+1}-f_{-1}}{2h}\\ \dfrac{\partial^2 f}{\partial x^2} &=& \dfrac{f_{+1}-2f_0+f_{-1}}{h^2}\\ \end{eqnarray*}

In case of border limit (when $x_{-1}$ or $x_{+1}$ are not computable), the foreward and backward computations are performed, respectively:

\begin{eqnarray*} \dfrac{\partial f}{\partial x } &=& \dfrac{f_{+1}-f_0}{h}\\ \dfrac{\partial^2 f}{\partial x^2} &=& \dfrac{f_{+2}-2f_{+1}+f_0}{h^2}\\ \end{eqnarray*}

and

\begin{eqnarray*} \dfrac{\partial f}{\partial x } &=& \dfrac{f_0-f_{-1}}{h}\\ \dfrac{\partial^2 f}{\partial x^2} &=& \dfrac{f_0-2f_{-1}+f_{-2}}{h^2}\\ \end{eqnarray*}

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.
