Abstract

Pan and Wang presented a generalized preconditioned Hermitian and skew-Hermitian splitting (GPHSS) method [J. Numer. Methods Comput. Appl., 32., 174-182, 2011] for saddle point problems. The method is improved to solve saddle point systems whose (1,1) block is a symmetric positive definite M-matrix with a new choice of the preconditioner and compared with other preconditioners. The results show that the new preconditioner outperforms the previous ones.
