摘要
This article proposes a generalized rotated shift-splitting (GRSS) iterative method for solving complex symmetric linear systems. Our analysis indicates that the proposed scheme is convergent. Spectrum features of some preconditioned matrices are also discussed. Finally, we report numerical experiments substantiating our theoretical findings.
