function varargout = wangya(varargin)
%WANGYA M-file for wangya.fig
%      WANGYA, by itself, creates a new WANGYA or raises the existing
%      singleton*.
%
%      H = WANGYA returns the handle to a new WANGYA or the handle to
%      the existing singleton*.
%
%      WANGYA('Property','Value',...) creates a new WANGYA using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to wangya_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      WANGYA('CALLBACK') and WANGYA('CALLBACK',hObject,...) call the
%      local function named CALLBACK in WANGYA.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
