% SYMBOL_DEMO M-file for symbol_demo.fig
% SYMBOL_DEMO, by itself, creates a new SYMBOL_DEMO or raises the existing
% singleton*.
%
% H = SYMBOL_DEMO returns the handle to a new SYMBOL_DEMO or the handle to
% the existing singleton*.
%
% SYMBOL_DEMO('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in SYMBOL_DEMO.M with the given input arguments.
%
% SYMBOL_DEMO('Property','Value',...) creates a new SYMBOL_DEMO or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before symbol_demo_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to symbol_demo_OpeningFcn via varargin.
