A New Tactics of Constructing High-order Accurate Quadrature Formula
摘要
Abstract
In this paper, a new general tactics of improving and constructing high-order accurate quadrature formula is presented to use low-order quadrature formula as a elementary building block by applying its expression of remainder term and concepts of algebraic accuracy. Similarly, finite number improving can be carried out. Finally, several examples of common low-order quadrature for- mulae are given to show higher validation of this method.关键词
