Einheiten in Simulink
R2026aSimulink ermöglicht es Ihnen, physikalische Einheiten als Attribute für Signale an den Grenzen von Modellkomponenten anzugeben. Indem Sie Signaleinheiten angeben, kontrollieren und visualisieren, können Sie die Konsistenz von Berechnungen in den verschiedenen Komponenten Ihres Modells sicherstellen. Diese zusätzliche Konsistenzprüfung kann zum Beispiel nützlich sein, wenn Sie viele separat entwickelte Komponenten in ein großes Gesamtsystemmodell integrieren. Für die ersten Schritte mit Einheiten, siehe Unit Specification in Simulink Models.
