     * %GUIDATA Store or retrieve application data.
     * %   GUIDATA(H, DATA) stores the specified data in the figure's
     * %   application data.
     * %
     * %   H is a handle that identifies the figure - it can be the figure
     * %   itself, or any object contained in the figure.
     * %
     * %   DATA can be anything an application wishes to store for later
     * %   retrieval.
     * %
     * %   DATA = GUIDATA(H) returns previously stored data, or an empty
     * %   matrix if nothing was previously stored.
     * %
     * %   GUIDATA provides application authors with a convenient interface
     * %   to a figure's application data. You can access the data from a
     * %   callback subfunction using the component's handle, without needing
     * %   to find the figure's handle.  You can also avoid having to create
     * %   and maintain a hardcoded property name for the application data
     * %   throughout your source code.  GUIDATA is particularly useful in
     * %   conjunction with GUIHANDLES, which returns a structure containing
     * %   handles of all the components in a GUI listed by tag.
     * %
     * %   Example:
     * %
     * %   Suppose an application creates a figure with handle F, containing
     * %   a slider and an editable text uicontrol whose tags are
     * %   'valueSlider' and 'valueEdit' respectively.  The following
     * %   excerpts from the application's M-file illustrate the use of
     * %   GUIDATA to access a structure containing handles returned by
     * %   GUIHANDLES, plus additional application-specific data added during
     * %   initialization and callbacks:
     * %
     * %   ... excerpt from the GUI setup code ...
     * %
     * %   f = openfig('mygui.fig');
     * %   data = guihandles(f); % initialize it to contain handles
     * %   data.errorString = 'Total number of mistakes: ';
     * %   data.numberOfErrors = 0;
     * %   guidata(f, data);  % store the structure
     * %
     * %   ... excerpt from the slider's callback ...
     * %
     * %   data = guidata(gcbo); % get the struct, use the handles:
     * %   set(data.valueEdit, 'String',...
     * %       num2str(get(data.valueSlider, 'Value')));
     * %
     * %   ... excerpt from the edit's callback ...
     * %
     * %   data = guidata(gcbo); % need handles, may need error info
     * %   val = str2double(get(data.valueEdit,'String'));
     * %   if isnumeric(val) & length(val)==1 & ...
     * %      val >= get(data.valueSlider, 'Min') & ...
     * %      val <= get(data.valueSlider, 'Max')
     * %     set(data.valueSlider, 'Value', val);
     * %   else
     * %     % increment the error count, and display it
     * %     data.numberOfErrors = data.numberOfErrors + 1;
     * %     set(handles.valueEdit, 'String',...
     * %      [ data.errorString, num2str(data.numberOfErrors) ]);
     * %     guidata(gcbo, data); % store the changes...
     * %   end
     * %
     * %   Note that GUIDE generates callback functions to which a structure
     * %   of handles is passed automatically as an input argument.  This
     * %   eliminates the need to call "data = guidata(gcbo);" in callbacks
     * %   written using GUIDE, unlike the example above.
