Refreshing app GUI during longer actions

I am designing a MATLAB app which, during a longer action, needs to update certain UI elements in order to indicate progress.

Unfortunately this does not happen. Instead the app GUI immediately jumps to its final appearance and somehow "consumes" the intermediate update steps.

I tried

refresh(app.UIFigure)

but that does not have an effect.

The only thing that helps (but to me is a very dirty work-around) is

pause(0.1)

after each GUI update.

Isn't there a better way?

Did you try drawnow()?

Seems to work great, thanks!
