摘要
考虑将预条件(I+S_α)应用于AOR迭代法和2PPJ迭代法,得到这两种预条件迭代法的收敛性定理,并从理论上证明了它们较原方法提高了迭代的收敛速度.
The precondition (I+α) is considered to be applied to the AOR iterative method and 2PPJ iterative method. Convergence theorems for the methods are obtained and it is theoretically proved that the convergent speed of the original methods has been improved,
