The CMRH method is an iterative method for solving nonsymmetric linear system Ax = b,
where A ∈ Cn×n, b ∈ Cn×1. The CMRH method is generally used with restarting to reduce
storage. Restarting slows down the convergence. In this paper we present a new technique for
accelerating the convergence of restarted CMRH algorithm. Finally, a numerical example is
given to illustrate the effectiveness of the presented method.
