A preconditioned MINRES method for block lower triangular Toeplitz systems
Congcong Li, Xuelei Lin, Sean Hon +1
In this study, a novel preconditioner based on the absolute-value block -circulant matrix approximation is developed, specifically designed for nonsymmetric dense block lower tr…

A block -circulant based preconditioned MINRES method for wave equations
Xue-lei Lin, Sean Hon
In this work, we propose an absolute value block -circulant preconditioner for the minimal residual (MINRES) method to solve an all-at-once system arising from the discretizatio…
