.. _R6.02.01: **r6.02.01** About decomposition methods like GAUSS ================================================================== **Summary:** This document shows a few aspects related to the decomposition method of GAUSS. After a quick overview, we recall the main advantages and disadvantages associated with this direct method. Then, we detail the implementation of algorithm LDLT implemented in the*Code Aster*. GAUSS (1777 - 1855) is at the origin of all direct methods for the numerical resolution of linear systems. Thank you for that here. **Table of Contents** .. toctree:: :hidden: self .. toctree:: :maxdepth: 2 :numbered: G_n_ralit_s_sur_les_m_thodes_de_type_GAUSS Inconv_nients_des_m_thodes_de_type_GAUSS M_thode_LDLT_par_blocs_mise_en_oeuvre_dans_Aster Bibliographie Description_des_versions_du_document
