A new preconditioned AOR iterative method for -matrices

Li et al. [Y.T. Li, C. Li, S. Wu, Improvements of preconditioned AOR iterative methods for L -matrices, J. Comput. Appl. Math. 206 (2007) 656–665] have considered the modified AOR method with a preconditioner ( I + S α ). In this paper, we present a new preconditioner ( I + S α β ) instead of ( I + S α ). The comparison theorems and numerical experiments show that the proposed new method can achieve faster convergence than the preconditioner introduced by Li et al.
