Matrix-Free Preconditioning using Partial Matrix Estimation
We consider matrix-free solver environments where information about the underlying matrix is available only through matrix vector computations which do not have access to a fully assembled matrix....

Preconditioner Updates for Solving Sequences of Linear Systems in Matrix-Free Environment
We present two new ways of preconditioning sequences of nonsymmetric linear systems in the special case where the implementation is matrix free. Both approaches updated preconditioner via function evaluations. Experiments with m...

The structure of invadopodia in a complex 3D environment
in a complex 3D environment, we observed invadopodial formation in cells grown on a dense matrix based on cell-free dermis. We have found that invadopodia differ in morphology when cells grown onthe dermis-based matrix...

Efficient Tridiagonal Preconditioner for the Matrix-Free Truncated Newton Method
In this paper, we study an efficient tridiagonal preconditioner, based on the directional differentiation, applied to the matrix-free truncated Newton method for unconstrained optimization. It is proved that this preconditioner is p...
