摘要
通过改进的谱修正迭代法,计算基于模拟电荷法的双连通区域数值保角变换的约束方程,得到了新的电荷点和变换半径,构造了近似保角变换函数.进而提出了新算法,并通过数值实验检验了新算法的有效性.
A new method for numerical conformal mapping of doubly-connected domain is considered.This method calculates the constraint equations of numerical conformal mapping based on charge simulation method of doubly-connected domain using the improvement of iteration method by correcting characteristic values,and the approximate conformal mapping function is constructed using new charge points and conformal mapping radius.The efficiency of the proposed method is illustrated by some numerical results.
