摘要
The solution of large linear discrete ill-posed problems by iterative methods has recently received considerable attention. This paper presents invertible smoothing preconditioners which are well suited for use with the GMRES, RRGMRES and LSQR methods. (c) 2004 IMACS. Published by Elsevier B.V. All rights reserved.
