Crear System objects

Escriba 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.
