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)

lda-0.2-matlab
matlab判别分析,基本思想是将高维的模式样本投影到最佳鉴别矢量空间,以达到抽取分类信息和压缩特征空间维数的效果,投影后保证模式样本在新的子空间有最大的类间距离和最小的类内距离,即模式在该空间中有最佳的可分离性。(matlab discriminant analysis, the basic idea is to sample the high-dimensional pattern projected onto the optimal discriminant vector space, in order to achieve the classification of information extraction and compression feature space dimension effect, the projected sample assurance model in the new subspace has the largest class room the intra-class distance and the minimum distance, i.e., have the best separability pattern in the space.)
