Fonctions Simulink
Vous pouvez utiliser les fonctions Simulink® pour définir des fonctions accessibles dans la hiérarchie de modèle Simulink. Une fonction Simulink calcule un ensemble de sorties en fonction des entrées fournies et du comportement implémenté de la fonction. Vous pouvez utiliser les fonctions Simulink pour :
Spécifier le prototype de fonction, qui comprend le nom de la fonction, les arguments en entrée et en sortie, par exemple
y = f(u).Implémenter le comportement de la fonction dans l’environnement Simulink en utilisant un bloc Simulink Function, une fonction exportée depuis un diagramme Stateflow® ou un bloc S-Function.
Appeler et réutiliser votre fonction dans l’ensemble de la hiérarchie de modèle.

Sélection d՚exemples
Model Service Access from Application Software Using Scoped Simulink Functions
Model services and accessing these services from a separate component.
Monitor Ink Status on Shared Printer Using Simulink Functions
How multiple clients can send requests to a server and receive a status from the server. Using Simulink® functions, different subsystems can call functions from other subsystems and interact in Simulink and Stateflow®. In this example, you model the ink status monitoring of a shared printer using Simulink functions.
Reuse Multiple Instances of a Simulink Function
To reuse components, use multiple instances of a function.
Dynamic Priority Scheduling of Functions
A common modeling pattern to dynamically schedule the execution of functions using a Stateflow® chart.
Temperature Control System Communicating with Messages
Distributed control of room temperatures by processing messages from room thermostats and communicating control commands using messages to different receivers.
Wireless Tire Pressure Monitoring System with Fault Logging
Model a wireless tire pressure monitoring system with fault logging using message communication.
