        I want to use Gauss-Legendre quadrature to evaluate a double integral. I came up with the following code. m=5000 I use the notation leg(x1, x2, m) to generate the weights and abscissas. Is there any other way to make this code run faster?

        The disadvantage of Gauss-Legendre quadrature is that there is no easy way to compute the node points and weights. See Quarteroni, Sacco, and Saleri, Section 10.2 and their program zplege.m for further information. Tables of values are generally available. We will be using a Matlab function to

        I came with a the following code to evaluate a double integral using Gauss Legendre quadrature in MatLab. I defined the function leg(x1,x2,m) in a different script to generate the weights and abscissas and I just call it in my code. My MatLab code runs significanlty slowly compared to
        The Gauss-Hermite quadrature weights that correspond to. nodes far away from 0 are usually very small in magnitude. These algorithms have been implemented in MATLAB and the numerical compar-isons are performed in that language. For the GLR algorithm we use the MATLAB
        In one dimension, Gaussian quadrature rules [29, 44] satisfy many of these desir-able properties Classical orthogonal polynomial families, such as the Legendre and Hermite polynomials, t this mold To prove this result, we require the additional assumption that the quadrature weights are positive
        Gauss-Legendre quadrature rules are of considerable theoretical and practical inter- est because of their role in numerical integration and interpolation. In addition, a series expansion useful for the computation of the Gauss-Legendre weights is derived. Together, these two expansions provide a
