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… WebMatlab has another efficient integration command called quadl, with the same input and output arguments. The method underlying quadl is a “Gaussian quadrature rule”. Recall that each Newton–Cotes quadrature rule came from integrating the Lagrange polynomial that interpolates the integrand f at n equally spaced nodes in the interval [a,b].
