ON THE SIMILARITIES BETWEEN THE QUASI-NEWTON INVERSE LEAST SQUARES METHOD AND GMRES

We show how one of the best-known Krylov subspace methods, the generalized minimal residual method (GMRes), can be interpreted as a quasi-Newton method and how the quasi-Newton inverse least squares method (QN-ILS) relates to Krylov subspace methods in general and to GMRes in particular when applied...
