Abstract
In this paper, we propose the PEκ method for solving a system of large scale linear algebraic equations with periodic block-tridiagonal matrix. Under the condition that the coefficient matrix is Hermitian positive definite, the solvability and convergence of the new method are proved, and the selection range for the parameter κ is given. For the example in this paper, the computation time of the PE2 method is only 50 percent of that of the SBGS method.
