L'arithmétique par intervalles permet de calculer et simultanément vérifier des résultats. Cependant, une application naïve de cette arithmétique conduit à un encadrement grossier des résultats. De plus, de tels calculs peuvent être lents.Nous proposons des algorithmes précis et des implémentations efficaces, utilisant l'arithmétique par intervalles, dans le domaine de l'algèbre linéaire. Deux problèmes sont abordés : la multiplication de matrices à coefficients intervalles et la résolution vérifiée de systèmes linéaires. Pour le premier problème, nous proposons deux algorithmes qui offrent de bons compromis entre vitesse et précision. Pour le second problème, nos principales contributions sont d'une part une technique de relaxation, qui ré...
