Efficient Numerical Integration Using Gaussian Quadrature

摘要

Simulation engineers are occasionally required to include numerical integration in this simulation models. The technique most often used is the simple "trapezoid method". In this short tutorial, we review Gaussian Quadrature techniques for ni- Mericla integration and show how careful Deployment of coefficient weights and se- Lection of the number o coefficients can Dramatically reduce the work required to Produce excellent numerical results.
