چکیده
|
We present a block preconditioner and consider block preconditioned ssor iterative methods for solving linear system ax=b. when a is an h-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. © 2013 zhao-nian pu and xue-zhong wang.
