摘要 利用预条件AOR迭代方法研究了线性方程组的迭代矩阵谱半径的收敛性问题,对古典的AOR迭代方法和预条件AOR迭代方法2种谱半径进行了比较,得到了一些比较定理,推广了前人相应的结果. By the preconditioned AOR iteration methods for solving linear systems,the convergence of the spectral radius of iterative matrix is studied.The preconditioned AOR iteration methods are compared with the classical AOR methods,and some comparison theorems of these methods are provided,some recent results are improved.
