摘要: 将小波分析方法应用于求解三维(3-D)边界元素法形成的线性方程组。通过数据压缩将稠密矩阵化为稀疏矩阵,当求解具有相同系数矩阵和多个不同右端向量的方程组时,可以节省计算量。

关键词: 小波分析, 边界元素法, 寄生参数, 线性方程组

Abstract: A wavelet analysis method is applied to solve the system of linear equations generated by the 3-D boundary element method.The dense matrix is converted into a sparse one through data compression.The calculation speed is improved while solving the system of linear equations with the same coefficient matrix and several different right hand sides.

Key words: wavelet analysis, boundary element method, parasitic parameter, system of linear equations
