% How I created this GUI in Matlab Version 7.0.0. (John Kruschke, March
% 2005.)
%
% At the Matlab prompt, I typed "guide". At the dialogue, I opened a blank
% figure.
%
% I dragged a pushbutton to the figure, and I dragged an axes to the
% figure. I resized them a bit, by clicking and dragging. By default,
% Matlab has tagged the pushbutton as "pushbutton1" and the axes as
% "axes1". (You can change the tags in the properties window if you want;
% the callback function names will also be changed to reflect the tags you
% choose.)
%
% I then went to View -> M-file Editor. The dialogue asked for a filename;
% I typed in the name. The editor then opened with this file, with just
% placeholders for the callback functions of the items in the figure.
%
% I then typed in three chunks of code: 
% 1. These comments at the top.
% 2. The initialization inside the function GuiExample_OpeningFcn
% 3. The action inside pushbutton1_Callback
% (Of course, I then saved this file.)
%
% To run, type this filename at the command line in Matlab, or, if guide is
% still open, press the play button on the guide window.

% GUIEXAMPLE M-file for GuiExample.fig
%      GUIEXAMPLE, by itself, creates a new GUIEXAMPLE or raises the existing
%      singleton*.
%
%      H = GUIEXAMPLE returns the handle to a new GUIEXAMPLE or the handle to
%      the existing singleton*.
%
%      GUIEXAMPLE('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUIEXAMPLE.M with the given input arguments.
%
%      GUIEXAMPLE('Property','Value',...) creates a new GUIEXAMPLE or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before GuiExample_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to GuiExample_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
