How to disable call back till I am done with Call back function

I have a call back function for capturing mouse moment.

set(gcf, 'WindowButtonMotionFcn', {@myCallBack, handles});

Inside the call back function I do some calculations.

 function myCallBack(varargin)
     hObject = varargin{1};
     mpos = get(hObject,'CurrentPoint');
     x = mpos(1);
     y = mpos(2);
     %perform a complex calculation
     varargin{3}.robot.MoveRobotxy(x,y);

The calculation performing is time intensive. Therefore when i run the code, callback function stop working after few seconds. Same thing happens when I put a 2 second pause instead calculations inside the call back.

   pause(2)

How do I avoid this? Is there a way to disable the call back till I am done with processing everything inside call back function?

Thank you

It is not clear what you want to achieve: once the callback has been triggered, it will run... and that will take how ever long the code will take. When exactly would you want to "disable" the callback? Are you trying to prevent it from being triggered again, once it is running?

You can use a persistent variable as a flag inside your callback function.

function myCallBack(varargin)
persistent CallbackRunning
if isempty(CallbackRunning) || ~CallbackRunning
     CallbackRunning = true ;
     hObject = varargin{1};
     mpos = get(hObject,'CurrentPoint');
     x = mpos(1);
     y = mpos(2);
     %perform a complex calculation
     varargin{3}.robot.MoveRobotxy(x,y);
     CallbackRunning = false ; % do not forget this :)
end
