Abstract

In this article, the parallel restarted generalized minimum residual [GMRES(m)] scheme has been implemented to solve large scale multilevel block Toeplitz matrix equations. The parallel fast Fourier transform has been used to accelerate the matrix‐vector multiplications in the iterative solver. The numerical results of electromagnetic scattering by cylindrical wire arrays demonstrate the accuracy and efficiency of the parallelization scheme. © 2009 Wiley Periodicals, Inc.

In this paper a novel iterative method of multilevel type for solving large-scale generalized eigenvalue problems encountered in structural dynamics is presented. A preconditioned iterative technique, which can be viewed as a modification of the Subspace Iteration method, is used for simultaneous ca
