How do I save state in app designer?

How do I save the state in app designer?

In other words, how do I save and restore the last value of a numeric field when opening an app made in app designer?

One way to do this is the following:

1. Save the value in a "CloseRequestFcn" callback function for you app to a MAT file: https://www.mathworks.com/help/matlab/ref/uifigureappdesigner-properties.html#property_CloseRequestFcn
2. In the app's "StartupFcn" callback function, load the value from the MAT file and set the numeric field with this value. The documentation for App Designer's startup callback function can be found at the following link: https://www.mathworks.com/help/matlab/creating_guis/app-designer-startup-function.html

The link for item 1 above is broken. TMW gave me this one instead: https://www.mathworks.com/help/matlab/ref/matlab.ui.figureappd-properties.html#bu4i700-1-CloseRequestFcn
