Gauss legendre python
WebGauss–Legendre rules. They have degree of exactness 2n −1 (and order 2n). Gauss–Legendre rules are open rules, and because the nodes are often positioned at irrational points in the interval, when we code the adaptive composite rules by repeatedly halving the interval, many extra function WebThe following python code allows you to run interactively either in a browser or using ipython notebook. It compares the trapezoidal rule and Gaussian quadrature with the exact result from symbolic python SYMPY up to 1000 integration points for the integral $$ I = 2 = \int_0^{\infty} x^2 \exp{-x} dx. $$ For the trapezoidal rule the results will vary strongly …
