Hey,
I want to update an image in the GUI from an external function. What I've found:
handles.image = image;
guidata(handles.axes1,handles.image??)
Axes has no callback function so I don't know where to start. And how do I specify which GUI I want to update?

imagesc(image, 'Parent', handles.axes1) solved my problem.

By 'external function', do you mean any callback function? We can replace the image using callbacks in GUIDE.
I created a new GUI using GUIDE with an axes and two Push Buttons and added the following callbacks for the buttons.(I have attached the files for your reference)
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
I = imread('rice.png');
axes(handles.axes1);
imshow(I);
% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton2 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
I = imread('saturn.png');
axes(handles.axes1);
imshow(I);
When you click pushbutton1, 'rice.png' will be displayed. The image will be replaced with 'saturn.png' when pushbutton2 is clicked.

I just mean a Matlab function. I found out that you can use 'Parent' for this. for example: imagesc(image, 'Parent', handles.axes1)
Thank you anyway
