Thanks for your valuable suggestion. I have a thousand of code inside the button where i refer some subfuction. Where i place this waitbar code?? please help me. Walter i tried a lot. I confused.

Is there a loop in the code? If so then waitbar() with a fraction of 0 before the beginning of the loop, and inside the loop probably as the last thing) update the fraction done.

If you want to print out specific words, like "code" and "loop" or "start of loop" and "end of loop" use fprintf() like this:

fprintf('Start of loop...\n');

fprintf('Inside loop, variable loopIndex = %d...\n', loopIndex);

fprintf('End of loop...\n');

The waitbar will _not_ close automatically: you need to close it in the program.

Divide your code into (say) 10 functional groups. At the end of each functional group, update the waitbar to represent that another group has finished. If you have a time-consuming loop inside one of the functional groups, divide the 10% (for the entire functional group) by the number of iterations for the loop, and each iteration through the loop, update the waitbar by that fraction.
