Hiii,
ich bin so ein Anfänger in C++, tut mir echt leid wegen der Frage jetzt...
Also habe eine .mat Datei jetzt mit diesem Code in C++ eingelesen. Auf diese Werte kann ich doch jetzt zugreifen oder? Das sind mehrere Array mit der Dimension 2. Wie macht man denn so etwas? Irgendetwas mit Pointern???
Danke im Voraus
Ich habe diese Frage in keinem Forum auf anderen Internetseiten gestellt.
