2. Stencil (numerical analysis) - Wikipedia

   en.wikipedia.org/wiki/Stencil_(numerical_analysis)

   The finite difference coefficients for a given stencil are fixed by the choice of node points. The coefficients may be calculated by taking the derivative of the Lagrange polynomial interpolating between the node points, [3] by computing the Taylor expansion around each node point and solving a linear system, [4] or by enforcing that the stencil is exact for monomials up to the degree of the ...

3. Five-point stencil - Wikipedia

   en.wikipedia.org/wiki/Five-point_stencil

   An illustration of the five-point stencil in one and two dimensions (top, and bottom, respectively). In numerical analysis, given a square grid in one or two dimensions, the five-point stencil of a point in the grid is a stencil made up of the point itself together with its four "neighbors".

4. Quincunx - Wikipedia

   en.wikipedia.org/wiki/Quincunx

   However, samples at the corner points are shared with adjacent pixels, so the number of samples needed is only twice the number of displayed pixels. [3] In numerical analysis, the quincunx pattern describes the two-dimensional five-point stencil, a sampling pattern used to derive finite difference approximations to derivatives. The five points ...
