A note on the preconditioned Gauss-Seidel method for M-matrices (vol 219, pg 59, 2008)

摘要

In this note, some errors in a recent article by Niki et al. [H. Niki, T. Kohno, M. Morimoto, The preconditioned Gauss-Seidel method faster than the SOR method, J. Comput. Appl. Math. 219 (2008) 59-71] are pointed out and a new proof for the corresponding result is presented.
