摘要:
在文[3]中作者们提出了几种求解线性系统的新迭代方法,与经典的Jacobi或Gauss-Seidel方法相比,这些方法可以被应用到更多的线性系统且有更快的收敛速度.通过分析和数值算例说明他们的方法适合更一般的矩阵,而不仅仅是文[3]作者提到的只适合正矩阵.

Comments on new iterative methods for solving linear systems
Wang Ke,Tan Lijun,Wang Shiheng
Abstract:
Some new iterative methods were presented by Du, Zheng and Wang for solving linear systems in [3], where it is shown that the new methods, comparing to the classical Jacobi or Gauss-Seidel method, can be applied to more systems and have faster convergence. This note shows that their methods are suitable for more matrices than positive matrices which the authors suggested through further analysis and numerical examples.
