本程序主要用来计算根据灰色理论建立的模型的预测值。 应用的数学模型是 GM(1,1)。 原始数据的处理方法是一次累加法- Of the procedures used to calculate the main theory in accordance with the gray of the predictive value of the model. The application of the mathematical model is GM (1,1). Hand

2012年全国大学生数学建模竞赛题目--葡萄酒的评价。文件中包含葡萄酒成分数据（Excel文件）、各种数据统计处理的MATLAB函数（已封装好，直接调用），包括：数据预处理、灰色预测、灰色关联度、基于熵权法的模糊综合评价、主成分分析、系统聚类、多元线性回归等程序。-Wines Evaluation from the title of 2012 National Undergraduate Mathematical ModelingContest. The file includes many M

两个MATLAB程序：层次分析法实现各个因子的权重系数求解；GN（1,1）模型进行灰色预测-Two MATLAB program: the analytic hierarchy process to realize the right of each factor weighting factor for solving GN (1,1) model of gray forecast

本程序将灰色预测和熵权法集合，构建出一个新的综合评价体系。该评价体系的权重结合了灰色预测和熵权法的优点。(This procedure combines the gray prediction and entropy method to construct a new comprehensive evaluation system. The weight of the evaluation system combines the advantages of gray prediction and

次为灰色预测法matlab程序，预测未来趋势并且能画出预测趋势(The second is the grey prediction matlab program, which predicts the future trend and draws the forecast trend.)
