Subspace Preconditioned LSQR for Discrete Ill-Posed Problems

Jacobsen, M.; Saunders, M., A.; Hansen, P., C.

Bit Numerical Mathematics — 2003, Volume 43, Issue 5, pp. 975-989

We present a novel implementation of a two-level iterative method for the solution of discrete linear ill-posed problems. The algorithm is algebraically equivalent to the two-level Schur complement CG algorithm of Hanke and Vogel, but involves less work per iteration. We review the algorithm
