Ok, I know this might not have been the best thing to do, but I created a GUI (say A_GUI) and accompanying m functions to do some analysis. I now copied everything into a new folder with the aim of altering the code and GUI for doing another type of analysis. So I changed the name A_GUI with, say, B_GUI everywhere in the GUI objects (Callback and CreateFcn handles) and the code itself. I still get this error for all the objects. How to solve this? Is it better to start from scratch again?
Undefined function 'A_GUI' for input arguments of type 'char'.
