GUI.m is the Guide Gui Matlab file which contains all the functions for CreateFcn, Callback, etc. When I run A.m from GUI.m (suppose I call A.m when I press a button from GUI), function A.m obviously will start doing stuff. However, I want to be able to change, for example, the text in a static text box of the GUI.m from within A.m while it is running. Unfortunately, I wasn't able to find a solution to this. Most threads revolve around calling an external function from within , let's say, a callback gui function.

The expectation is fairly simple: I want to change the content of a GUI static text box from any external function I wish: even command line.

To change the text from within the A.m function, you will need the handle of the text box:
set(handle, 'String', 'I just modified it.');

If you do not have this and need it, then you need to rewrite your program. Sorry to be so blunt...

But, a really crappy way to do this is to get the children of the figure and search for the one you want, perhaps by the properties Tag, Style, String, Position, or UserData. Hopefully it has some property that differs from the other uicontrol objects.
