Discrete cosine transform LSQR and GMRES methods for multidimensional ill-posed problems
M. El Guide, A. El Ichi, K. Jbilou
In the present work, we propose new tensor Krylov subspace method for ill posed linear tensor problems such as in color or video image restoration. Those methods are based on the t…

RBF approximation of three dimensional PDEs using Tensor Krylov subspace methods
M. El Guide, K. Jbilou, A. Ratnani
In this paper, we propose different algorithms for the solution of a tensor linear discrete ill-posed problem arising in the application of the meshless method for solving PDEs in…
