function varargout = view3d(varargin)
%VIEW3D GUI for interactive viewing of 3D Volumes
%   VIEW3D is used view orthographic slices of 3D volumes
%    
%   Type in an expression that generates a 3D array
%   then press the Display button
%
%   3D expressions such as: rand(50,40,30) or
%   the name or a 3D array variable in the workspace
%
%   The 3 views (all except the lower right one)
%   display orthographic projections
%
%   Use the scroll bars to change the number of the slice viewed
%
%   Use the transpose, flipud, or fliplr to
%   transpose the view, flip it vertically, or horizontally
%
%   Use Update 3D to view the slices in a 3D view
%
%   Check auto to obtain an automatic update 
%   of the 3D view of the slices
%   (Note: this may affect performance)
%
%   Use cla to clear the 3D view this may improve performance
%
%   Change the span values to the volume''s physical dimensions
%   so the aspect ratio is displayed properly
%   (note: you can use relative values
%   for example use 1,3,2 instead of 0.5,1.5,1.0
%   then press Span

%| ABOUT CALLBACKS:
%| GUIDE automatically appends subfunction prototypes to this file, and 
%| sets objects' callback properties to call them through the FEVAL 
%| switchyard above. This comment describes that mechanism.
%|
%| Each callback subfunction declaration has the following form:
%| <SUBFUNCTION_NAME>(H, EVENTDATA, HANDLES, VARARGIN)
%|
%| The subfunction name is composed using the object's Tag and the 
%| callback type separated by '_', e.g. 'slider2_Callback',
%| 'view3d_CloseRequestFcn', 'axis1_ButtondownFcn'.
%|
%| H is the callback object's handle (obtained using GCBO).
%|
%| EVENTDATA is empty, but reserved for future use.
%|
%| HANDLES is a structure containing handles of components in GUI using
%| tags as fieldnames, e.g. handles.view3d, handles.slider2. This
%| structure is created at GUI startup using GUIHANDLES and stored in
%| the figure's application data using GUIDATA. A copy of the structure
%| is passed to each callback.  You can store additional information in
%| this structure at GUI startup, and you can change the structure
%| during callbacks.  Call guidata(h, handles) after changing your
%| copy to replace the stored original so that subsequent callbacks see
%| the updates. Type "help guihandles" and "help guidata" for more
%| information.
%|
%| VARARGIN contains any extra arguments you have passed to the
%| callback. Specify the extra arguments by editing the callback
%| property in the inspector. By default, GUIDE sets the property to:
%| <MFILENAME>('<SUBFUNCTION_NAME>', gcbo, [], guidata(gcbo))
%| Add any extra arguments after the last argument, before the final
%| closing parenthesis.
