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

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.)
