A rational Arnoldi approach for ill-conditioned linear systems

Claude Brezinski, Paolo Novati, Michela Redivo-Zaglia

For the solution of full-rank ill-posed linear systems a new approach based on the Arnoldi algorithm is presented. Working with regularized systems, the method theoretically recons…
