Gaussian Quadrature - Department Of Mathematics
Gaussian Quadrature In Lecture 26, we learned that a Newton-Cotes quadrature rule with nnodes has degree at most n. Therefore, it is natural to ask whether it is possible to select the nodes and weights of an n-point quadrature rule so that the rule has degree greater than n. ... Access This Document
