Modified SNS and SSS iteration methods for a class of complex symmetric linear systems
Shi-Liang Wu, CuiXia LI · Scientia Sinica Mathematica · 2014
In this paper, based on the previous work by Bai, the modified skew-normal splitting (MSNS) and skew-scaling splitting (MSSS) iteration methods are presented to solve a broad class of complex symmetric linear systems. It is shown that the MSNS and MSSS iteration methods are unconditionally convergent. The corresponding inexact MSNS (MSSS) method is developed by employing some Krylov subspace methods. Numerical experiments are reported to illustrate the efficiency of the proposed methods.
