MATLAB: How to change the lamp color while the application is running

colorlamplampcolorstatelampstatus

Hi everybody!
I want to inroduce a lamp in my applycation, that shows the status of the application.
-Grey: introducing data.
-Red: calculating.
-Green finished.
The PROBLEM is that while the aplication is running the lamp color doesn´t change. When introducing the data it is grey, as it is set, but when I press the calculation button, it doesn`t change color to red, even if it is the first comand in the code. It seems like the application cannot send the order in real time.
I tried the following and no one worked:
  • Switch command.
  • Lamps states.
  • Internal function.
Any suggestion to get the lamp red while runnig and green when finished?
Thanks!

Use drawnow() to give MATLAB a chance to update the screen.
