Abstract

We prove that, under certain conditions, some classical iterative methods converge for the linear system resulting from a fourth-order compact discretization of the convection-diffusion equation.

Key words: Linear systems, iterative methods, fourth-order compact discretization scheme, convection-diffusion equation.
