• saddle point problem
• iterative method
• preconditioned GMRES

In this paper, we discuss some more generalized iterative schemes for solving the large sparse saddle point problems proposed by Ling and Hu [X.F. Ling, X.Z. Hu, On the iterative algorithm for large sparse saddle point problems, Appl. Math. Comput. 178 (2006) 372-379.], and apply the preconditioned GMRES to accelerate the convergence. Numerical experiments are reported that show the effectiveness of the proposed methods.
