Convergence of Relaxed Matrix Parallel Multisplitting Chaotic Methods for H-Matrices

open access: yesJournal of Applied Mathematics, 2014
Based on the methods presented by Song and Yuan (1994), we construct relaxed matrix parallel multisplitting chaotic generalized USAOR-style methods by introducing more relaxed parameters and analyze the convergence of our methods when coefficient ...

The role of numerical integration in numerical homogenization*

open access: yesESAIM: Proceedings and Surveys, 2015
Finite elements methods (FEMs) with numerical integration play a central role in numerical homogenization methods for partial differential equations with multiple scales, as the effective data in a homogenization problem can only be ...

Impact of Accuracy Optimization on the Convergence of Numerical Iterative Methods

open access: yes, 2015
Among other objectives, rewriting programs serves as a useful technique to improve numerical accuracy. However, this optimization is not intuitive and this is why we switch to automatic transformation techniques. We are interested in the optimization of numerical programs relying on the IEEE754 floating-point arithmetic.
