摘要:
给出了矩形域上一顶点为奇点的非正常积分的近似计算以及优化中心数值算法,此种算法避免了函数值的大量重复计算,采用外推法减少了迭代次数,可尽快达到符合精度要求的近似值,且提出的优化数值算法便于在计算机上进行计算.
Abstract:
The approximate calculation of the abnormal integral of the singularity on the vertex of the rectangular domain and the optimization center numerical algorithm are given, which avoids a large number of repeated calculations of function values, uses the extrapolation method to reduce the number of iterations, and can reach the approximate value that meets the accuracy requirements as soon as possible, and the proposed optimized numerical algorithm is convenient for calculation on the computer.
