27 Algorithme de calcul "*ExtendedKalmanFilter*"
28 ---------------------------------------------
30 .. ------------------------------------ ..
31 .. include:: snippets/Header2Algo01.rst
33 Cet algorithme réalise une estimation de l'état d'un système dynamique par un
34 filtre de Kalman étendu, utilisant un calcul non linéaire de l'état et de
35 l'évolution incrémentale (processus).
37 Dans le cas d'opérateurs réellement non-linéaires, on peut aisément utiliser
38 l':ref:`section_ref_algorithm_EnsembleKalmanFilter` ou
39 l':ref:`section_ref_algorithm_UnscentedKalmanFilter`, qui sont souvent
40 largement plus adaptés aux comportements non-linéaires mais plus coûteux. On
41 peut vérifier la linéarité des opérateurs à l'aide de
42 l':ref:`section_ref_algorithm_LinearityTest`.

73 Cette liste indique les noms des variables supplémentaires qui peuvent être
74 disponibles à la fin de l'algorithme. Cela implique potentiellement des
75 calculs ou du stockage coûteux. La valeur par défaut est une liste vide,
76 aucune de ces variables n'étant calculée et stockée par défaut. Les noms
77 possibles sont dans la liste suivante : [
