You do know that there can be several workspaces, right? The base workspace, and then each function will have it's own local workspace.

 If you want to access data that is in base workspace in your gui functions,
 use 
 v = evalin('base','name of variable u want to access');
 % the variable's data is now stored in v.
 If u want to save data of ur gui work space to base,use
 assignin('base','name of variable u want to save','value of variable');
