二重奇异积分近似计算的一种优化算法

An Optimum Algorithm for Approximate Evaluationof Twodimensional Singular Integrals

本文对于矩形区域上某一内点为奇点的奇异积分的近似计算给出了优化中心数值算法，它在迭代计算过程中避免了函数值的重复计算．采用外推法减少迭代次数．

This paper presents an optimum numerical algorithm of center rule for the approximate evaluation of singular integrals over rectangular domains with a inner singularity. With the algorithm, values of the integrand can be avoided to be computed repeatedly.
