Block preconditioned SSOR methods for \(H\)-matrices linear systems (Q2375436)

Summary: 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.
