摘要 提出了一种对称化线性双共轭梯度(BiCG)迭代算法,应用于光电工程领域中波导问题的分析。该算法是针对有限元线性系统系数矩阵的大型复对称特性,在常规BiCG迭代法基础上对其进行对称化所得到的快速迭代求解算法。数值结果表明,所提出的对称BiCG迭代法比若干常用方法更加有效。 A symmetric Bi-conjugate Gradient(BiCG) iterative algorithm is proposed to analyze waveguide problems in photoelectric engineering.This efficient algorithm is based on the BiCG iterative algorithm and designed especially for the large,complex and symmetric FEM linear equations.Numerical result shows the effectiveness of the proposed method by comparisons with some standard iterative methods.
