为了在高性能计算机上求解增广线性系统,基于并行多分裂的两种技巧,本文提出一种局部多分裂迭代格式,给出当增广线性系统的矩阵为M-矩阵和H-矩阵时新方法的收敛性理论.并讨论预条件矩阵的特征值情形.
In this paper,we present a local-multisplitting iterative method based on two kinds of multi-splitting techniques for the augmented linear systems.The convergence of the new splitting iterative method are studied when the coefficient matrix of the augmented linear systems is an M-matrix and an H-matrix.Finally,we discuss the eigenvalues of preconditioned matrix.
