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?

Numerical integration: Gaussian quadrature rules. Matlab’s built-in numerical integration function Fortunately, the roots of the Legendre polynomials and their corresponding weights have been Gauss-Legendre rules are open rules, and because the nodes are often positioned at irrational
Key words. quadrature, Gauss-Legendre, Gauss-Jacobi, asymptotic expansion. The C and Fortran codes are interfaced with MATLAB via MEX les. See Figure 4.3 for analogous plots of quadrature error Gauss-Legendre is the most commonly used of the Gaus-sian quadrature rules.
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

Gauss Legendre Quadrature When numerical analysts seak of Gaussian quadrature without further qualification, they tyically mean Gauss Legendre Moreover, the weights are smaller at these ends of the interval. The table below shows nodes and weights for n = 4, as comuted in MATLAB. j nodes, x j
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
In numerical analysis, Gauss-Legendre quadrature is a form of Gaussian quadrature for approximating the definite integral of a function. For integrating over the interval [?1, 1], the rule takes the form: where. n is the number of sample points used, wi are quadrature weights
