wait
An image acquisition object stops running or logging when one of the following conditions
is met:
• The stop function is issued.
• The requested number of frames is acquired. This occurs when
FramesAcquired = FramesPerTrigger * (TriggerRepeat + 1)
where FramesAcquired, FramesPerTrigger, and TriggerRepeat are properties
of the video input object.
• A run-time error occurs.
• The object's Timeout value is reached.
Examples
Create a video input object.
vid = videoinput('winvideo');
Specify an acquisition that should take several seconds. The example sets the
FramesPerTrigger property to 300.
vid.FramesPerTrigger = 300;
Start the object. Because it is configured with an immediate trigger (the default),
acquisition begins when the object is started. The example calls the wait function after
calling the start function. Notice how wait blocks the MATLAB command line until the
acquisition is complete.
start(vid), wait(vid);
