摘要：
In this paper we apply the AOR method to preconditioned linear systems different from those considered in Evans and Martins (Internat. J. Comput. Math. 5 (1995) 69-76), Gunawardena et al. (Linear Algebra Appl. 154-156 (1991) 123-143) and Li and Evans (Technical Report No. 901, Department of Computer Studies, University of Loughborough, 1994). Our results show that some improvements in the convergence rate of this iterative method can be obtained. (C) 2001 Elsevier Science B.V. All rights reserved.
