Five-point stencil
From Wiki @ Karl Jones dot com
In numerical analysis, given a square grid in one or two dimensions, the five-point stencil of a point in the grid is made up of the point itself together with its four "neighbors".
Description
It is used to write finite difference approximations to derivatives at grid points.
It is an example for numerical differentiation.
