waitbarr

WAITBAR Display wait bar.
   H = WAITBAR(X,'title', property, value, property, value, ...) 
   creates and displays a waitbar of fractional length X.  The 
   handle to the waitbar figure is returned in H.
   X should be between 0 and 1.  Optional arguments property and 
   value allow to set corresponding waitbar figure properties.
   Property can also be an action keyword 'CreateCancelBtn', in 
   which case a cancel button will be added to the figure, and 
   the passed value string will be executed upon clicking on the 
   cancel button or the close figure button.

   WAITBAR(X) will set the length of the bar in the most recently
   created waitbar window to the fractional length X.

   WAITBAR(X,H) will set the length of the bar in waitbar H
   to the fractional length X.

   WAITBAR(X,H,'updated title') will update the title text in
   the waitbar figure, in addition to setting the fractional
   length to X.

   WAITBAR is typically used inside a FOR loop that performs a 
   lengthy computation.  A sample usage is shown below:

       h = waitbar(0,'Please wait...');
       for i=1:100,
           % computation here %
           waitbar(i/100,h)
       end
       close(h)
