摘要
本文给出了一种修正的PST方案.此修正方案可以减少PST迭代过程中计算Green函数或矩阵求逆次数,从而可以降低PST 方法运算量.
This paper presents a modified scheme for the PST method.This scheme is char-acterized by greatly reducing the calculation of Green's function or ofthe inverse ma-trix once every m circles in the process or iteration so as to reduce the computing costof PST to some degree.
