Application of the Jacobi Davidson method for spectral low-rank preconditioning in computational electromagnetics problems

Mas Marí, José; Cerdán Soriano, Juana Mercedes; Malla Martínez, Natalia; Marín Mateos-Aparicio, José (Springer, 2015-01)

[EN] We consider the numerical solution of linear systems arising from computational electromagnetics applications. For large scale problems the solution is usually obtained iteratively with a Krylov subspace method. It ...
Block approximate inverse preconditioners for sparse nonsymmetric linear systems

Cerdán Soriano, Juana Mercedes; Faraj El Guelei, Táher; Malla Martínez, Natalia; Marín Mateos-Aparicio, José; Mas Marí, José (KENT STATE UNIVERSITY, ETNA, DEPT MATHEMATICS & COMPUTER SCIENCE, KENT, USA, OH, 44242-0001, 2010)

[EN] In this paper block approximate inverse preconditioners to solve sparse nonsymmetric linear systems with iterative Krylov subspace methods are studied. The computation of the preconditioners involves consecutive updates ...
