A Flexible Global GCRO-DR Method for Shifted Linear Systems and General Coupled Matrix Equations
In this paper, we mainly focus on the development and study of a new global GCRO-DR method that allows both the flexible preconditioning and the subspace recycling for sequences of shifted linear systems. The novel method presented here has two main advantages: firstly, it does not require the right...
