My GUI was running perfectly well before I tried to change one little thing (it was only to print something to the screen, it shouldn't have made a difference). Suddenly I started getting this message
Undefined function 'Stacks' for input arguments of type 'struct'.
Error in @(hObject,eventdata)Stacks('Stack1_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating uicontrol Callback
Now even when I use my Time Machine to try to get back to old version of the GUI that I know for a fact worked they will not either.
Has anyone had anything similar happen or does anyone have any advice? I already tried restarting MATLAB.
