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

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
