The ophir powermeter's Event has input parameters to determind which device fires the event.
However it seem Matlab does not support event with input parameters? not like C++
C = actxcontrol('mwsamp.mwsampctrl.2',[0 0 200 200]);
It seem Matlab only support event name (char) vs event handler (func) pairs
I know how to pass parameter to event handler, the problem is , who to pass parameter to the event itself.
