# calcul de paramètres dans un système de matrice sous matlab

## calcul de paramètres dans un système de matrice sous matlab

(OP)
Bonjour !
je dispose d'une équation d'un modèle de prédiction de la neige au sol qui est la suivante:

Sn = Sn-1 + a(Tav - b) + cPs -dPl
avec : Tav, Ps, Pl des vecteurs d'une matrice de dimension (19710x6) et a, b, c et d des paramètres réels.
So = niveau initial de la neige au sol
Sn = niveau de la neige au sol au jour n avec n = 1:19710
pour n =0 alors So = 12 ( initial).

Comment faire le calcul pour avoir les valeurs de a, b, c, et d ? aidez moi je veux savoir comment chercher les valeurs de a, b, c et d en utilisant matlab.
merci
