摘要：

In this paper, we point out that the generalized iteration method presented in a recent paper 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] belongs to the inexact Uzawa algorithm, and an improper statement in a theorem in that paper is corrected. (C) 2008 Elsevier Inc. All rights reserved.
