摘要
本文将文献[1]的结果推广到二维情形,得到了相应的计算二重积分的高精度求积公式及其复合型公式。它具有辛普生公式的优点,但代数精确度比辛苦生公式提高2阶。 本文数值试验表明,这个新的高精度数值积分公式是十分有效的。
This paper discusses the following quadrature rule with higher degree of accuracyandits Compositrule are presented aswell:which possess the all advantages of Simpsons rule, but the degree of accuracy isincreased by two order than Simpson's rule.The numerical tests that the quadrature formula of this paper is very efficient.
