Sharing Data Between GUI...

Hi everybody! I've a problem : i needed to share data between 3 different GUIs that i've created using GUIDE. Now I've used the 'setappdata/getappdata' solution, specifing the MAtlab root in the function (something like setappdata(0,'new_var_name',var_name)). I need to have the data saved during a session available even after a restart of Matlab program. Is this possible? If yes, how? thanks a lot for any help :D

You can, at select points in your code, save a bunch of parameters to a file with a name you have chosen, to record the "current" state of your GUI and other stuff.
When your GUI is initialising, or when the user presses a "load" command, you can load in that file, and do "stuff" to make the gui go into the correct state.
If you want the user to select the file to save, or load, the functions uigetfile and uiputfile will help.

"save" and "load" will save and reload those parameters. If you want them to be unreadable, you'll need to use lower level functions to do the job.

Did you see the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F
What I do is to save all those settings into a mat file that gets read in when your GUI starts.
