-  Present the essential of the main numerical methods in algorithm form most used in matrix numerical analysis in solving systems of linear and non-linear equations taking into account the accuracies  from the point of view of speed of convergence, stability, improve the precision of the numerical results, minimization of errors on the results .

In parallel, we show how to implement (write and run)these algorithms in the form ''computer program''.

Ce cours a l'objectif de  montrer l’importance des mathématiques et à les rendre plus concrètes en donnant des exemples de leurs applications pratiques comme en Physique, en Biologie, en Finance, en Théorie de l’Information, en Physique, en Recherche Opérationnelle.
