摘要
本文给出由Euler-Maclaurin求和公式构造不含导数项的修正复化梯形公式的一般方法,并按该方法给出了收敛阶分别为O(h^6)和O(h^8)的两个公式。它们与复化梯形公式有相同的计算量,但收敛阶大为提高。
In this paper,a genera] method of constructing modified compound trapezoidal rules of numerical integration is given,and two concrete rules are given with this method. Numerical results are presented wich also show that they are simple and efficient numerical integration rules.
