InitialTriggerTime
Purpose Record absolute time of first trigger
Description The InitialTriggerTi me property records the absolute time of the first
trigger. The absolute time is reco r de d as a MATLAB clock vector.
For all trigger types,
InitialTriggerTime records the time when the
Logging property is set to 'on'.
To find the time when a subsequent trigger executed, view the
Data.AbsTime field of the EventLog property for the particular trigger.
Characteristics
Access Read only
Data type
Six-element vector of doubles (MATLAB clock vecto r )
Valu es The defa ult value is [].
Examples Create an image acquisition object, vid, for a USB -b ased we bca m .
vid = videoinput('win video',1);
Start the object. Because the TriggerType property is set to
'immediate' by default, the trigger executes immediately. The object
records the time of the initial trigger.
