摘要 在预条件矩阵(P=I+B)下提出新的AOR迭代法,讨论了新方法的收敛性,并给出预条件AOR迭代法与经典AOR迭代法之间的比较定理。最后给出一个数值例子验证该预条件要优于通常的预条件(I+S)。 Under the preconditioned matrix(P=I+B),a new AOR iterative method is discussed,presenting the convergence quality of the method.This paper also gives the comparison theorems between the proposed AOR iterative method and the classic AOR iterative method.Then a numerical example is given,which explain the precondition iterative method is better than(I+S).
