Dear all,

I am attempting to write a callback function in MATLAB; a routine that calls a function every time a condition is satisfied, i.e. an event driven routine running in real-time. The condition, in my case, is receiving a meaningful frame from a sensor, i.e. Leap Motion controller.

Matlab has built-in callback functions that are associated with GUIs, e.g. 'WindowButtonMotionFcn' that can be used in the format "set (gcf, 'WindowButtonMotionFcn', @mouseMove)". My objective is to have an event driven routine similar to 'WindowButtonMotionFcn', but the event that calls my function, e.g. @FrameArrival, is the arrival of a data frame from my sensor rather than moving the mouse cursor over the current figure !

Could I possibly write such a call back function that is not attached to a graphic object or GUI ?

Regards,

Bashar
