How to call a sub function written in GUI from another GUI?

5 views (last 30 days)
I have written a program which has a few user interface. Each user interface is a GUI. I want to call a sub function written in one GUI after I close the other. For example, I have a interface to select some attributes, and I need to use these attributes in a function at the main GUI after I press the select button and close it an when the focus returned to the main form.
Is there anyway to call the sub functions of a GUI from another GUI?
Thanks

A similar question has been asked before.
Please see the link :
Essentially, in the CloseRequestFcn of the first GUI, you'll call the other GUI you want to use, and pass data to the other GUI.

Thank you for your answer.
The problem is that the other GUI is already working, meaning I have the GUI 1. I push a button in that Form, and it opens GUI 2. Now I select some options provided in this GUI, then I close it by accepting this options. Then when the focus goes to the GUI 1 and I need it to run a function using the choices I made in GUI 2.
It is a really typical situation in for example VB, however, I could not find out how to approach it in Matlab! For example, using your suggestion, can I call a sub function in GUI 1 in CloseRequestFcn of the GUI 2?
Thank you
