Yes, did you read the FAQ? use setappdata to store it and getappdata to retrieve it.
■Storing data in the application workspace using the SETAPPDATA and GETAPPDATA functions.
% Do this to save variables to your figure's workspace.
% handles.GUIHandle is the "Tag" property of your main GUI figure.
% Double-click figure to bring up the "Property Inspector" in GUIDE.
setappdata(handles.GUIHandle, 'yourVariable', yourVariable)
% Do this to retrieve variables from your figure's workspace.
yourVariable = getappdata(handles.GUIHandle , 'yourVariable')
% Do this to remove what you saved from your figure's workspace.
rmappdata(handles.GUIHandle, 'yourVariable')
You could also set to the root directory, i.e. 0., that way stuff is stored even after you close the GUI.
%Set
setappdata(0,'myStuff',stuff);
%Extract
mystuff = getappdata(0,'mystuff')
