Additive Average Schwarz Method for Elliptic Mortar Finite Element Problems with Highly Heterogeneous Coefficients
Ali Khademi, Leszek Marcinkowski, Sanjib Kumar Acharya +1
In this paper, we extend the additive average Schwarz method to solve second order elliptic boundary value problems with heterogeneous coefficients inside the subdomains and across…

Iterative regularization algorithms for image denoising with the TV-Stokes model
Bin Wu, Leszek Marcinkowski, Xue-Cheng Tai +1
We propose a set of iterative regularization algorithms for the TV-Stokes model to restore images from noisy images with Gaussian noise. These are some extensions of the iterative…

MATLAB Implementation of Element-based Solvers
Leszek Marcinkowski, Jan Valdman
Rahman and Valdman (2013) introduced a vectorized way to assemble finite element stiffness and mass matrices in MATLAB. Local element matrices are computed all at once by array ope…
