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