Efficient Krylov-Regularization Solvers for Multiquadric RBF Discretizations of the 3D Helmholtz Equation
Mohamed El Guide, Khalide Jbilou, Kamal Lachhab +1
Meshless collocation with multiquadric radial basis functions (MQ-RBFs) delivers high accuracy for the three-dimensional Helmholtz equation but produces dense, severely ill-conditi…
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…
Tensor Krylov subspace methods via the T-product for color image processing
M. El Guide, A. El Ichi, K. Jbilou +1
The present paper is concerned with developing tensor iterative Krylov subspace methods to solve large multi-linear tensor equations. We use the well-known T-product for two tensor…
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
