On iterative solving of linear algebraic equations in p-h-version of finite element method

The goal of this paper is investigation of the efficiency of iterative preconditioned cojugate gradient methods for solving linear systems of equations which arise in p-h-version of finite element methods. The results of numerical experiments are presented for the model boundary value problem with different values of h, p and iterative parameters. Some conclusions on the comparative costs of algorithms are made on the base of analysis of matrix structure of linear systems.
