摘要
给出了一类预条件的AOR迭代法及其收敛性,并给出了松驰因子ω与加速因子γ的选取对收敛速度的影响,同时通过数值实例验证了主要结果.
In this paper,a type of the AOR pre-condition iterative method and its convergence are obtained,and we get the relaxation factorωand acceleration factorγon effect of the rate of convergence.Also,we verify our main results through the numerical example.
