Crear System objects

Escribir una clase de MATLAB^® que cree y defina un nuevo System object™

Para poder definir un System object propio, se deben personalizar los métodos de implementación. Use herramientas gráficas para explorar la extensa API y crear System objects. Por ejemplo, se pueden insertar métodos para inicializar, ejecutar, restablecer y terminar System objects. Para ver una introducción a la definición de un System object, consulte Define Basic System Objects.

Métodos

Temas

Introducción a la escritura de System objects

Define Basic System Objects

Create a basic System object with the stepImpl method.

Atributos de propiedad

Specify property attributes to limit the type, visibility, and value of properties.

Entrada y salida

Change the Number of Inputs
This example shows how to set the number of inputs for a System object™ with and without using getNumInputsImpl.
Define Composite System Objects
Define System objects that include other System objects as properties.
Handle Input Specification Changes
Implement methods to restrict when System object input complexity, data type, or size can change or implement a method to react when input specifications change.
