在线性方程组Ax=b的系数矩阵A为三对角L矩阵的前提下,提出了新的预条件矩阵P=I+S1下的USSOR迭代方法.运用USSOR迭代方法及矩阵的分裂理论,获得了新的比较定理.通过数值例子验证了所得的结论.%Under the premise of the linear equations Ax = b coefficient matrix A is tridiagonal L matrix, the new preconditioned matrice P=J+S1 is provided. Using USSOR iterative methods and the theory of matrix splitting,the new comparison theorems are obtained. Finally, the main results are demonstrated by numerical examples.
