Hi,
Ich habe mal die Suche beansprucht und auch was passendes gefunden jedoch wurde dort kein Lösung für mein Problem gepostet, nun noch einmal.
Das Problem liegt darin, dass nach einiger Zeit mein Programm abstürzt während getsnapshot mit folgendem crash-file:
MATLAB crash file:C:\Users\Andreas\AppData\Local\Temp\matlab_crash_dump.7380-1:

Funktion ohne Link?

ich hoffe ihr könnt mir hier etwas helfen, das Programm sollte eigentlich while(1) laufen bzw while(trigger) die picID ist im moment nur vorhanden um eben die Dauer ein bisschen zu begrenzen.
