I use MATLAB 7.1. If I open an existing GUI project built in 6.5 MATLAB
with GUIDE tool, .fig is loaded correctly but .m is not loaded (it has
the same name of .fig), then when I run the GUI and click on buttons I
got function not found errors:
??? Undefined command/function 'fsv'.

??? Error while evaluating uicontrol Callback.
How can I reassociate .m with his .fig?
