I am an experienced GUIDE user. But I am still a beginner in manual GUI design. I am trying to implement a callback that will effectively push an "Update" button that already exists on a GUI periodically. This update button performs some tasks and updates the uitable in the main GUI figure window. I'm trying to determine the best approach. So far, I have tried a solution that involves pushing button "A" in the GUI, which does something, then starts an infinite while loop witin the A callback function calls the Update callback button. However, locks up Matlab's computational capacity until control-C is administered. I expect there is a much better approach. Any advice or links to appropriate content would be much appreciated.
