预条件P(S)=I+(S)下的USSOR迭代方法及其比较定理
Comparison theorems for USSOR iterative methods with the precondition P(S)=I+(S)
摘要
Abstract
In order to improve the convergence rate of linear equations iterative method, using the appropriate pretreatment is necessary > that is the case Pax=Pb. After putting preconditioned matrix Ps = I+ S into USSOR iterative method and discussing the convergence when coefficient matrix is a nonsingular M matrix by using the theory of matrix splitting,a comparison theorem is obtained. And then the explanations are given as well as some specific numerical examples.关键词
