hey folks, two simple questions :D
function GetData_Callback(hObject, eventdata, handles)
x = str3num(get(handles.editbox1,'String'))
function UseData_Callback(hObject, eventdata, handles)
y = x +1
disp(y)
How can I pass x form the 1st Button to the 2nd Button ?

请先登录，再回答此问题。

Do you necessarily need to create x in the GetData_Callback? Why not just in the UseData_Callback? If you really need it this way, just initialize the variable x in the main function (before the callbacks start). Then the variable will be valid in the entire file (in all subfunctions).

You can use the handles structure of your GUI to store variables.
eg:
function GetData_Callback(hObject, eventdata, handles)
handles.x = str3num(get(handles.editbox1,'String')) % store in handles structure
guidata(handles,hObject) % update structure
function UseData_Callback(hObject, eventdata, handles)
y = handles.x +1
disp(y)
That should work :)
