Parameters:

Inherits from: solveur_sys_base

Cholesky direct method.

Parameters:

[impr] (type: flag) Keyword which may be used to print the resolution time.
[quiet] (type: flag) To disable printing of information

Inherits from: solveur_sys_base

Optimal is a solver which tests several solvers of the previous list to choose the fastest one for the considered linear system.

Parameters:

seuil (type: float) Convergence threshold
[impr] (type: flag) To print the convergency of the fastest solver
[quiet] (type: flag) To disable printing of information
[save_matrice | save_matrix] (type: flag) To save the linear system (A, x, B) into a file
[frequence_recalc] (type: int) To set a time step period (by default, 100) for re-checking the fatest solver
[nom_fichier_solveur] (type: string) To specify the file containing the list of the tested solvers
[fichier_solveur_non_recree] (type: flag) To avoid the creation of the file containing the list

Synonyms: gmres

Inherits from: solveur_sys_base

Preconditioned GMRES.

Parameters:

[diag] (type: flag) Keyword to precondition with the diagonal
[seuil] (type: float) Value of the final residue. The solver ceases iterations when the Euclidean residue standard ||Ax-B|| is less than this value. default value 1e-12.
[impr] (type: flag) Keyword which is used to request display of the Euclidean residue standard each time this iterates
[save_matrice | save_matrix] (type: int) To save the matrix in a file.
[quiet] (type: flag) To not displaying any outputs of the solver.
[nb_it_max] (type: int) Keyword to set the maximum iterations number for the solver.
[controle_residu] (type: int) Keyword of Boolean type (by default 0). If set to 1, check the convergence after solve
