| Abstract: | For augmented linear systems, Bai, et al. studied the generalized SOR method （Bai Z Z, Parlett B, Wang Z Q. methods for augmented linear systems. 1-38） and obtained the optimal iteration optimal iteration parameters is given in On generalized successive overrelaxation Numerische Mathematik, 2005, 102（1）： parameters. Another short proof for the this paper, which will be very useful for investigating the optimal iteration parameters of other stationary iteration methods with parameter acceleration. |
