A Study Of Iterative Method For Large Complex Linear Equations

Large sparse complex linear systems arise in many scientific computing and engineering applications,and its rapid solution is of great practical significance.In order to solve such problems effectively,in this paper,based on the method of matrix splitting,a new iterative scheme with parameter is proposed.The convergence conditions of this iterative method are theoretically analyzed.Besides,the upper bound of the corresponding spectral radius and a theoretical expression of quasi optimal parameters are also given.Finally,we verify the feasibility and effectiveness of this method through experiments.
