mohamad - have you read through the working with triggers to see how to set a Manual Trigger (which may be what you are doing)? Do you have to configure the trigger type with
triggerconfig(vidobj, 'manual')
?

Unfortunately, I don't have the Image Acquisition Toolbox so cannot provide much more help. Perhaps someone more familiar with this toolbox will be able to.

For those still looking, initialize the camera before trying to trigger it:
cam = videoinput('gentl', 1); %specify video object
triggerconfig(cam, 'manual'); %allow for manual frame triggering
start(cam) %initialize
trigger(cam); %trigger
