Abstract. In 1986 , the GMRES method and it5 restarted version 、 GMRES ( Tn ) m8thod , were proposed by Saad and Schultz for solving Fonsymmetric linear 5yste1 皿 s 、 In this paper 、 we investigate the restart of the GMRES ( m ) method , The main goal of this paper is to propose an extension of the GMRES ( m ) method based on a new fra 皿 ework of the restart ・ Amathe 皿 乱 tical background of the extensio コ 1 is analyzed based on the error equations . The numerlcal results are presented to show a
