灰色关联度分析及灰色预测--by 数协潘天宇
灰色关联度分析及灰色预测,本函数是根据GM(1,1)模型所编写而成的,大致思想是:
% 对于一些有噪声的数据,通过一次累加生成,使其变为较为有规律性的数据,通过对于该数据的预测从而实现对于原数据的预测。(Grey correlation analysis and grey prediction)

PCA
函数作用:
cwstd.m——用综合标准化法标准化矩阵
Cwfac.m——计算相关系数矩阵,计算特征向量和特征值,对主成分进行排序,计算各个特征值的贡献率,挑选主成分(贡献率达与85 ),输出主成分个数,计算主成分载荷
Cwscore.m——计算各主成分得分,综合得分并排序
Cwprint.m——读入数据文件,调用以上三个函数,并输出结果
原始数据:存储在src.txt中是一个30×8的矩阵
敲入命令:
(PCA)
