摘要
考虑线性系统Ax=b,当A为L-矩阵时,通过利用AOR迭代方法收敛的谱半径与预优AOR方法的比较,给出了在二级迭代的情况下,外迭代的R1-收敛因子更为精确的结果.
This paper examines the linear system Ax = b when A is a L - matrix. Given two-stage iteration, a comparison was drawn between spectral radii of AOR and preconditioned AOR methods, aiming at more accurate results of R1 - factor of the outer iteration of two-stage iterative.
