Tensor GMRES and Golub-Kahan Bidiagonalization methods via the Einstein product with applications to image and video processing
M. El Guide, A. El Ichi, F. P. A Beik +1
In the present paper, we are interested in developing iterative Krylov subspace methods in tensor structure to solve a class of multilinear systems via Einstein product. In particu…
Tensor extrapolation methods with applications
F. P. A. Beik, A. El Ichi, K. Jbilou +1
In this paper, we mainly develop the well-known vector and matrix polynomial extrapolation methods in tensor framework. To this end, some new products between tensors are defined a…
On the preconditioning of three-by-three block saddle point problems
Hamed Aslani, Davod Khojasteh Salkuyeh, Fatemeh Panjeh Ali Beik
We establish a new iterative method for solving a class of large and sparse linear systems of equations with three-by-three block coefficient matrices having saddle point structure…
