What do you mean by 'always have access to it'? Do you mean actually 'always' or just for the duration of the GUI being open.
If you mean always then I would assume xlswrite is the correct approach if your data is from a .xlsx file. I have never used that personally though as I always save data from Matlab to a .mat file using
save( filename, 'variable1', 'variable2', etc)
If you mean you want the data for the duration of the GUI then attach it to the handles struct as e.g = ...
guidata( hObject, handles );
Then in any other callback of the GUI you can just access it as
