一、简介
1 名称由来
灰色模型（Gray Model）,邓聚龙教授1982年提出。
常见系统分类：
白色系统是指一个系统的内部特征是完全 已知的，即系统的信息是完全充分的。
黑色系统是指一个系统的内部信息对外界来说是一无所知的，只能通过它与外界的联系来加以观测研究。
灰色系统内的一部分信息是已知的，另一部分信息是未知的，系统内各因素间有不确定的关系。

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