Multistep matrix splitting iteration preconditioning for singular linear systems
Keiichi Morikuni
Multistep matrix splitting iterations serve as preconditioning for Krylov subspace methods for solving singular linear systems. The preconditioner is applied to the generalized min…

Inner-iteration preconditioning with a symmetric splitting matrix for rank-deficient least squares problems
Keiichi Morikuni
Stationary iterative methods with a symmetric splitting matrix are performed as inner-iteration preconditioning for Krylov subspace methods. We give conditions such that the inner-…
