摘要
对于系数矩阵为不可约的Z-矩阵的大型线性方程组,给出了一类新的预条件AOR迭代法,并证明其在给定的条件下是收敛的,数值例子证明解的有效性.
This paper presented a new preconditioned AOR - type iterative method for solving the linear system, where coefficient matrix was an irreducible Z-matrix. And some theorems and corollaries were given to show that the new preconditioned A0R iterative method was convergence under the given condition. Numerical example verifies the validity.
