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

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