J'ai essayé de rendre cet exemple le plus générique possible.

La matrice A a 5 colonnes et 3 lignes. Elle peut donc de manière aléatoire avoir entre 2 et 4 variables libres. 

double **Ab = r_singular_Ab_mZ(i_Abr_Ac_bc_mZ(R3,R5,C1),999);

La matrice Ab_free a 5 colonnes réservé pour b. Cela permet de gérer des matrices qui ont entre 2 et 4 variables libres. 5 colonnes c'est à dire 4 pour les variables libres et une pour b. Les colonnes de variables libres non utilisés sont nulles. 

 double **Ab_free =             i_Abr_Ac_bc_mZ(R5,R5,C5);
