solution of large scale indefinite linear systems by using a Krylov subspace method, and describe the iterative construction of … Krylov subspace method is used, as by product, to provide an approximate inverse preconditioner. Then, we experience our … use a Krylov subspace method to both approximately solve the Newton equation and to construct the preconditioner to be …
