高维广义积分近似计算的优化中心算法

Optimum Center Algorithm for Approximate Evaluationof High Dimensional Singular Integrals

对于长方体区域上的任一内点为奇点的广义积分的近似计算给出了优化中心数值算法，它在计算过程中避免了函数值的重复计算，采用外推法加速达到精度要求。

This paper presents an optimum numerical algorithm of center rule for the approximate evaluation of singular integrals over threedimensional rectangular domains with an inner singularity. With the algorithm, the repeated computation of values of the integrand can be avoided.
