I have created a waitbar as follows:
h = waitbar(0,'1','Name','Approximating pi...',...
To kill this waitbar, we have to use delete(h) instead of close(h).
The problem is that during the development and testings, it is possible that the h variable is cleared or overwritten. Then the waitbar is still present but the handle is lost. In that case, how can I close the waitbar? Of course, clicking the closing X button does not work.
Thanks for your support.
