Abstract

In this paper, we improve the preconditioned AOR method of linear systems considered by Evans et al. [The AOR iterative method for new preconditioned linear systems, Comput. Appl. Math. 132 (2001) 461-466]. In Evans' paper, the coefficient matrix of linear system have to be an L-matrix with a"i","i"+"1a"i"+"1","i0, i=1,...,n-1 and 0
