MATLAB-Klassen
Sie können Code für MATLAB-Funktionen generieren, die Wertklassen, Handle-Klassen und System objects verwenden. Mehr über Wert- und Handle-Klassen in MATLAB erfahren Sie unter Comparison of Handle and Value Classes. Mehr über System objects erfahren Sie unter What Are System Objects?.
Im MATLAB Programmcode zur Codegenerierung können Sie:
eine MATLAB-Wert- oder -Handle-Klasse im MATLAB Programmcode verwenden.
eine MATLAB-Wertklasse als Eingabeargument für einen MATLAB-Einstiegspunkt verwenden.
Beim Generieren von C Code werden MATLAB-Klassen als Strukturen dargestellt. Wenn Sie C++ Code generieren, besteht das Standardverhalten des Codegenerators darin, C++ Klassen für die MATLAB-Klassen zu erzeugen. Bei der Verwendung von Klassen in Ihrem MATLAB Programmcode für die Codegenerierung müssen Sie bestimmte Anwendungshinweise und Beschränkungen beachten.
