| Abstract: | In this paper, the authors consider the solution of linear systems of large nonsymmetric saddle point problems by modifying the algorithm in 3]. The convergence of the modified algorithm is analyzed, and at the same time, numerical experiments are presented to illustrate the effectiveness of the modified algorithm. |
