Block Preconditioned SSOR Methods forH-Matrices Linear Systems

[摘要] We present a block preconditioner and consider block preconditioned SSOR iterative methods for solving linear systemAx=b. WhenAis anH-matrix, the convergence and some comparison results of the spectral radius for our methods are given. Numerical examples are also given to illustrate that our methods are valid.
