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。
對于繫數矩陣為不可約的Z-矩陣的大型線性方程組,給齣瞭一類新的預條件AOR迭代法,併證明其在給定的條件下是收斂的,數值例子證明解的有效性。

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 AOR iterative method was convergence under the given condition.Numerical example verifies the validity.
