Recycling Preconditioners for Sequences of Linear Systems and Matrix Reordering
… to solve linear systems and we always look for methods that are faster and/or require less storage. In this dissertation, we focus on solving these systems with Krylov subspace methods and how to obtain effective preconditioners inexpensively. We first present an application for electronic …
