Convergence properties of the proposed method are studied. Some numerical experiments of the ISSOR method are given to compare with that of the well-known SOR-like and MSSOR methods. %K augmented system %K symmetric positive denite %K SOR-like %K MSSOR %K improved SSOR %U http://journals.math.tku.edu.tw/index.php/TKJM/article/view/688
