Restarted block Lanczos bidiagonalization methods
Date of Original Version
The problem of computing a few of the largest or smallest singular values and associated singular vectors of a large matrix arises in many applications. This paper describes restarted block Lanczos bidiagonalization methods based on augmentation of Ritz vectors or harmonic Ritz vectors by block Krylov subspaces. © Springer Science+Business Media B.V. 2006.
