Dear Community,
I've been going round and round the Matlab documentation and available threads for some time now and I couldn't manage to find a solution to this: Let's say I have function A.m and GUI.m. A.m has one big function with lots of things in it. 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.
I would really appreciate your support. Thank you very much.
Regards,
Alex
P.S.: is there a way of doing it in a simple was as?:
%line in A.m
GUI(set(handle.statictext,'String','EUREKA'));
I understand that the GUI functions are "nested" so inaccessible to the A.m but I was hopping that there would be a way of calling the handles in something similar to this. 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.
Thank you

You just have to send back whatever variable you are manipulating in the main function to the GUI and the code you have there works fine. I just tried it. Or make the variable global.

The question is not clear:
  1. ... suppose I call A.m when I press a button from GUI ...
  2. ... Most threads revolve around calling an external function from within , let's say, a callback gui function.
This means, that most thread concern exactly your problem. Then they should help you already.
One of the many solutions to share data between a GUI and any other function:
function buttonCallback(hObject, EventData, handles)
% This is the callback of the button, which starts the external function.
GuiHandle = ancestor(hObject, 'figure');
A(rand(1,2), rand(3,4), GuiHandle); % Or how ever it is called
And the function header of the external function:
function output = A(in1, in2, GuiHandle)
handles = guidata(GuiHandle);
set(handles.statictext, 'String', 'Written from external function!');

Hello Simon,
Thank you for your quick reply. Indeed, this is what I was looking for. I'm new to Guide Gui since I only used the normal gui interface until now; now I have to understand the guide gui data management. In my case I have an A(GuiHandles) function with no outputs and I call it from the callback of a pushbutton. Again, thanks!
Regards, Alex
