I suggest that you copy inputdlg.m to a new file, edit the function name
to the new name, and search down in there for uiwait() and use the
two-argument form of uiwait() to put a limit on the time waited. You may
also need to add a couple of lines to set the values to 0 in the case
the timeout is detected. You can tell that the timeout was hit because
if the timeout was hit then the handle being waited on is still a valid
handle for ishandle() and if the user responded instead of timing out
then ishandle() on that handle will be false.

I have always wondered to what extent the Matlab EUL allows for this.
