THE COMPARISON OF RIGHT PRECONDITIONED AND LEFT PRECONDITIONED IN KRYLOV SUBSPACE METHODS [PDF]

, 2014
To the problem of large-scale systems of linear equations, we describe the comparisonof left preconditioned and right preconditioned. We used the preconditioned method usingthe left and right for each methods of Krylov subspace methods, and inspect the ...

Tensor-Krylov Methods for Large Sparse Systems of Nonlinear Equations

, 2007
In this paper, we describe tensor methods for large sparse systems of nonlinear equations based on Krylov subspace techniques for approximately solving the linear systems that are required in each tensor iteration. We refer to a method in this class as a

Krylov Subspace Methods with a Twist

Krylov subspace methods are widely used iterative solvers for real or complex linear systems. In this talk, I will advocate that these methods should be viewed as more than just algorithms juggling matrices and vectors. Instead, with a view towards the setting behind the linear systems, we will systematically re-derive a general residual minimizing ...
