Generalizations of Sylvester's determinantal identity
Anna Karapiperi, Michela Redivo-Zaglia, Maria Rosaria Russo
In this paper we deal with the noteworthy Sylvester's determinantal identity and some of its generalizations. We report the formulae due to Yakovlev, to Gasca, Lopez--Carmona, Rami…
Embedded techniques for choosing the parameter in Tikhonov regularization
Silvia Gazzola, Paolo Novati, Maria Rosaria Russo
This paper introduces a new strategy for setting the regularization parameter when solving large-scale discrete ill-posed linear problems by means of the Arnoldi-Tikhonov method. T…
A GCV based Arnoldi-Tikhonov regularization method
Paolo Novati, Maria Rosaria Russo
For the solution of linear discrete ill-posed problems, in this paper we consider the Arnoldi-Tikhonov method coupled with the Generalized Cross Validation for the computation of t…
Preconditioning linear systems via matrix function evaluation
Paolo Novati, Michela Redivo-Zaglia, Maria Rosaria Russo
For the solution of discrete ill-posed problems, in this paper a novel preconditioned iterative method based on the Arnoldi algorithm for matrix functions is presented. The method…
