Funciones de Simulink

Cree funciones accesibles en los modelos de Simulink

Una función de Simulink^® es una unidad computacional que calcula un conjunto de salidas cuando se proporciona un conjunto de entradas. Dado que una función de Simulink proporciona una interfaz de texto común para definir su función y un llamador a función, la forma de definirla es decisión suya. Las posibles definiciones de la función incluyen el uso de:

Bloques de Simulink en un bloque Simulink Function
Transiciones de estado de Stateflow^® en una función gráfica de Stateflow exportada
Instrucciones de código de MATLAB^® en una función MATLAB Function de Stateflow exportada

Después de definir una función, puede llamarla mediante un bloque Function Caller, MATLAB Function o un gráfico de Stateflow.

Monitoring Ink Status on a Shared Printer Using Simulink Functions

How clients, in this case three computers, can send jobs to a server, a printer, and receive status from that server. This example highlights how Simulink functions can be called from different subsystems and interact in both Simulink® and Stateflow®. (Note that when you simulate the example, Stateflow might generate code in the current working folder.)

Model Reusable Components Using Multiply Instanced Simulink Functions

In this example, the model slexCounterFunctionMdlRef contains the Simulink® function update, which maintains a counter. Multiple instancing provides the ability to reuse this logic as CounterA and CounterB in this example model.
