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 exact result for po… Web• For Gauss-Legendre integration, we allowed both weights and integration point locations to vary to match an integral exactly more d.o.f. allows you to match a higher degree polynomial! • An alternative way of looking at Gauss- Legendre integration formulae is that we use Hermite interpolation instead of Lagrange interpolation!
