摘要
讨论了将奇偶划分应用于非对称分块三对角方程组的方法及所得方程组的性质。
A method based on block odd even reduction for nonsymmetric tridiagonal linear system is discussed. The properties of the reduction linear system are also discussed. In order to improve the rate of convergence, this paper also gives a preconditioner by minimizing the Frobenius norm of matrix.
