Hi; I want to get the coefficient of the Legendre-Gauss Quadrature, I find this method is fast, but when the integration result is big, then the result is not accurate enough, I think it is because I only use 5 coefficient to compute it. Do you think it will be accurater when I use more coefficients to compute? Is possible to get 16 coefficients to compute? The 6 coefficients I use are from: http://mathworld.wolfram.com/Legendre-GaussQuadrature.html I need more coefficients to get accurater result. How about the method of the Integration function built-in Mathematica? Thanks, Chen
