I've pointed you in the direction of the 2 functions you need to solve your problem. Have a look at the help and the examples (plus any FEX that Titus linked you to).
Once you've tried some coding if its still not working come back with some detailed questions on your specific code.

It all depends on your estimate on how much already has been done. Robert noted already the relevant functions: start a timer. In the timer function you update the waitbar (function waitbar). This is pretty straight forward. One of two things need to be done though: either your script needs to update something such that the timer knows how much has already been done. Or, you need an estimate about how long your script will be running.
Take a look at the file exchange for various waitbar enhancements ...

Modify this code to suit your needs:
t = timer('TimerFcn', 'stat=false; disp(''Timer Done!'')','StartDelay',10);
start(t);
stat=true;
count = 0;
f = waitbar(0,'Start');
while(stat==true)
count = count + 1;
f = waitbar(count/10,f,[num2str(10-count),' sec remaining']);
pause(1);
end
delete(t);
delete(f);

Or alternatively put the waitbar execution within the timer:
f = waitbar(0,'Start');
count = -1;
t = timer('TimerFcn', 'count = count + 1;f = waitbar(count/10,f,[num2str(10-count),'' sec remaining'']);','ExecutionMode','fixedDelay','Period',1);
start(t);
pause(10);
stop(t);
delete(t);
delete(f);
