摘要 讨论一类新的多参数预条件AOR迭代法的收敛性,得到了比较定理,说明此类预条件AOR迭代法的收敛速度要比经典AOR迭代法的收敛速度快。最后,用一个数值例子验证了得到的结论。 In this paper,we discuss the convergence of a new preconditioned AOR iterative method with a multi-parameters preconditioner and obtain the comparison theorems.It shows that the convergence rate of the preconditioned AOR iterative method is faster than that of the basic AOR iterative method.Finally,a numerical example is given to illustrate the theorems.
