I have created a GUIDE figure that contains an edit box, and then I have assigned a callback function to that edit box that executes whenever the user enters a new string into the edit box.

However, I have the need to call this callback from outside the figure (e.g. the command line) as if it's being executed by the edit box itself. I need to do this so that I can trigger some functionality that is very specific to that callback and the UI object and figure to which it's attached.

My callback function looks like this:

edit1_Callback(hObject, eventdata, handles)

How can I call this callback function from the command line or from anywhere else?

Here is example code that outlines one approach to do this. For illustration purposes, I am assuming that your GUIDE application is called "myGUI".

h = myGUI;
handles = guidata(h); %The "guidata" function is used to retrieve the "handles" structure from the figure or any of its components.
hObject = handles.edit1; %This assumes that your edit box has its object "Tag" property set as "edit1".  Please revise as needed.
eventdata = []; %If your callback does not specifically need/use "eventdata", then you can supply an empty array.
myGUI('edit1_Callback',hObject,eventdata,handles) %This line of code is used to call "edit1_callback" and provide it the relevant input arguments.
