It is reported in [1] that the convergence rate of the IMGS method, with the preconditioner $I+S_{\alpha}$, is superior to that of the basic SOR iterative method for the $M$-matrix. This paper considers the preconditioned Jacobi (PJ) method with the preconditioner $P=I+S_{\alpha}+S_{\beta}$, and proves theoretically that the convergence rate of the PJ method is better than that of the basic AOR method. Numerical examples are provided to illustrate the main results obtained.
