Code-Verifikation
Nach der Generierung von Code können Sie den Quellcode und die Ausgabeergebnisse zur Verifikation untersuchen. Der Codegenerierungs-Bericht bietet eine interaktive Schnittstelle zur Untersuchung der generierten C/C++ Quelldateien, generierten Datentypen und weiteren Informationen zum Code. Über das Berichtinformations-Objekt können Sie programmatisch auf eine Untermenge der Informationen im Codegenerierungs-Bericht zugreifen. Sie können die Ausgabe des generierten MEX-Codes gegenüber dem ursprünglichen MATLAB®-Code testen oder benutzerdefinierte Tests auf Basis der MATLAB-Unittest-Klassen erstellen. Sie können Laufzeitfehler-Prüfungen generieren, die Sie auf Fehler während der Code-Ausführung hinweisen.
