Laufzeitdaten aus der Simulation speichern

Speicherung von Simulationsdaten wie Ausgabe, Signal, Zeit, Zustand und Datenspeicherprotokolldaten

Sie können während der Simulation Simulationsdaten im MATLAB^®-Workspace oder in einer Datei, einschließlich einer MLDATX-Datei, MAT-Datei oder Excel^®-Datei, speichern, um sie später abzurufen und nachzubearbeiten. Die Simulationsdaten können eine beliebige Kombination von Ausgangs-, Signal-, Zeit-, Zustands- und Datenspeicherprotokollierungsdaten enthalten.

Das Speichern von Simulationsdaten im Dataset-Format vereinfacht die Nachbearbeitung, da es ein einheitliches Format für die Ergebnisse einer Vielzahl von Protokollierungstechniken bietet. Mithilfe des Formats Dataset werden die Daten als MATLAB timeseries oder timetable-Objekte gespeichert, die Sie mit MATLAB verarbeiten können.

Um festzustellen, welche Methode Sie für Protokollierungsdaten verwenden sollten, siehe Save Simulation Data.
