function varargout = shiyan1fig(varargin)
% SHIYAN1FIG M-file for shiyan1fig.fig
%      SHIYAN1FIG, by itself, creates a new SHIYAN1FIG or raises the existing
%      singleton*.
%
%      H = SHIYAN1FIG returns the handle to a new SHIYAN1FIG or the handle to
%      the existing singleton*.
%
%      SHIYAN1FIG('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in SHIYAN1FIG.M with the given input arguments.
%
%      SHIYAN1FIG('Property','Value',...) creates a new SHIYAN1FIG or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before shiyan1fig_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to shiyan1fig_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
