GUI error: Undefined function 'A_GUI' for input arguments of type 'char'.

4 views (last 30 days)
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?

It is possible to repair it, with some work, but the easier approach is to go back to your A_GUI and tell GUIDE to save it under a new name.
