Getting output from an app into the calling workspace

I have a MatLAB script that runs fine. I want to add a GUI at the front of the app to make it easier for the user. I am using appdesigner for the GUI. The MatLAB script calls the app at the beginning. This part works ok. The app lets the user select an entry, a number from a drop down list, and store it in the app's workspace in a variable called numSelect. The drop down list is populated fine and when I select an entry from the drop down list it is stored fine in numSelect. I cannot figure out how to get the selected number, numSelect, from the app's workspace into the workspace of the calling script. I have searched the community forums and MatLAB help but have not found how to do this.

Turn the script into a function and have the app execute it instead.

This doesn't help as the script outputs a numeric array to the workspace at present. If I call the script from the app, I still need the numeric array returned into the base workspace.

A function will return its return variable when it terminates -- have the app terminate and return to the command line when the function completes its work.

Scripts are to be avoided, anyways...except for just playing at the command line.

This question has been asked before, and there are a few different answers threads with ideas for how to do this. Here are two:

• How can I work around the fact that app designer does not support output arguments?
• Output arguments in App Designer

AFter some digging at the links and some trial and error, I was able to get an app to output data to teh calling script. The app acts as a GUI.
