摘要: 本文提出了几种SIP算法,并讨论了系数矩阵为L-阵时,最优参数的选取。数值结果表明这几种算法和选取的最优参数的确比用其它算法和参数好。

Abstract: In this paper several SIP algorithms are proposed and the choice of their optimal parametens are analyzed in the case where the coefficient matrix of the linear system is an L-matrix with nonvanishing diagonal elements. Numerical results are given to illustrate that the convergence of our algorithms with the optimal parameters is better than that of other algorithms and parameters.
