A block preconditioning cost analysis for solving saddle-point linear systems
We investigate the cost of preconditioning when solving large sparse saddlepoint linear systems with Krylov subspace methods. To use the block structure of the original matrix, we apply one of two block preconditioners. Algebraic eigenvalue analysis is given for a particular case of the precondit...
