585Graphics and GUI

that will execute asynchronously, enabling the synchronous callback to complete its work

sooner. This will ensure better GUI responsiveness, without affecting the program logic.

Here is a simple example (we may wish to specify some more timer properties — the snip-

pet below is only for illustration):

% Regular callback function - takes a long time to complete

function myCallbackFcn(varagin)

% Call the utility function directly (synchronously)

utilityFcn();

end

% A better callback - completes much faster, using asynchronous timer

function myCallbackFcn(varagin)

% Start an asynchronous timer to perform the lengthy ...
