In numerical analysis, a quadrature rule is an approximation of the definite integral of a function, usually stated as a weighted sum of function values at specified points within the domain of integration. (See numerical integration for more on quadrature rules.) An n-point Gaussian quadrature rule, named after Carl Friedrich Gauss, is a quadrature rule constructed to yield an …

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".

17.06.2020 · Subtract 1 from the five-point rating (to adjust the scale to start at 0). Multiply by 6/4 (the maximum value of a 0–6 point scale divided by the maximum value of a 0–4 point scale), which stretches the scale. Add back the 1 (to adjust the scale again). Table 3 shows the application of this formula.
