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