function varargout = ex55_1(varargin)
% ex55_1 M-file for ex55_1.fig
% ex55_1, by itself, creates a new ex55_1 or raises the existing
% singleton*.
%
% H = ex55_1 returns the handle to a new ex55_1 or the handle to
% the existing singleton*.
%
% ex55_1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in ex55_1.M with the given input arguments.
%
% ex55_1('Property','Value',...) creates a new ex55_1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before ex55_1_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to ex55_1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
