function varargout = tuxiangchuli(varargin)
%TUXIANGCHULI M-file for tuxiangchuli.fig
% TUXIANGCHULI, by itself, creates a new TUXIANGCHULI or raises the existing
% singleton*.
%
% H = TUXIANGCHULI returns the handle to a new TUXIANGCHULI or the handle to
% the existing singleton*.
%
% TUXIANGCHULI('Property','Value',...) creates a new TUXIANGCHULI using the
% given property value pairs. Unrecognized properties are passed via
% varargin to tuxiangchuli_OpeningFcn. This calling syntax produces a
% warning when there is an existing singleton*.
%
% TUXIANGCHULI('CALLBACK') and TUXIANGCHULI('CALLBACK',hObject,...) call the
% local function named CALLBACK in TUXIANGCHULI.M with the given input
% arguments.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
