It has recently been reported that the convergence of the preconditioned Gauss-Seidel method which uses a matrix of the type (I+ U) as a preconditioner is faster than the basic iterative method. In this paper, we generalize the preconditioner to the type (I+flU), where fl is a positive real number.
