Probleme avec une S-Function

Bonjour je commence juste à travail sur des S-Function, je n’arrive pas à réaliser une fonction très simple je voudrais recopier le résultat de l’entrée en sortie. Pouvez vous me dire ou se trouve mon erreur.

Code:

Merci

Bonjour, je vous propose ce code simple qui recopie le résultat de l'entrée en sortie comme vous l'avez demandé.
