The wait bar does not close and prevents matlab from closing

Good evening, I created a program that uses a waitbar in a function, defined as follows:

F = waitbar(0,"1",'Name',"Calcolo cinematica inversa");

for u = 1:count
    
    ...

    if getappdata(F,'canceling')
        close(F);
        return;
    end
    waitbar( u/count,F, sprintf('Calcolo %d di %d.',u,count) );

end

close(F);

the problem is that the close (F) function does not cause the waitbar to close, which remains open. The window showing the waitbar cannot be closed in any way except by restarting matlab, which in this situation can only be closed by forcing it to stop. Matlab continues to work correctly in all other functions and the program can be launched again causing the appearance of a new waitbar which, too, cannot be made to disappear. Has this happened to anyone?

Hi,

Generally, this type of behaviour occurs when you have “Cancel button” added to your "waitbar" and trying to remove the wait bar box using “close()”. In such cases, you must use “delete ()” instead of “close ()” to remove the wait bar dialogue box.

Hope this helps!

Very well, with delete() it works! Thanks!
