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