The MATLAB Implementation of Generalized Unsteady Multisplitting Iterative Methods for Positive Semidefinite System

为了解大型稀疏半正定线性方程组,文章主要研究广义非定常多分裂迭代算法及其MATLAB实现.文章给出广义非定常多分裂迭代算法,并给出其收敛性定理.然后,利用MATLAB软件对该算法进行了实现.并且该算法明显优于Jacobi迭代算法.

To solvelarge semidefinite sparse linear equations,we study the generalized unsteady multisplitting iteration algorithm and its MATLAB realization.The paper gives the generalized unsteady multisplitting iterative algorithm,and its convergence.Finally,the MATLAB realization of this algorithm is mentioned and this algorithm is obviously better than the Jacobi iteration algorithm.
