Implementierung von Blöcken mit System objects
MATLAB System-Blöcke verwenden ein System object, um MATLAB®-Algorithmen in Simulink zu implementieren. Bevor Sie einen MATLAB System-Block verwenden können, benötigen Sie ein System object, das Sie mit einem Block verknüpfen können. Ein System object ist eine bestimmte Art von MATLAB-Klasse, die speziell für die Implementierung und Simulation von dynamischen Systemen entwickelt wurde. Weitere Informationen zum Implementieren und Erstellen von System objects finden Sie unter Create System Objects.
