MATLAB統(tǒng)計(jì)工具箱實(shí)例分析

1、MATLAB統(tǒng)計(jì)工具箱實(shí)例分析利用irmtldb從Excle中導(dǎo)入一組有關(guān)iris（鶯尾屬植物）的數(shù)據(jù)，從Sepal.length （花萼長(zhǎng)度），Sepal.width （花萼寬度）,Petal.length （花瓣長(zhǎng)度），Petal.width （花 萼寬度）四個(gè)方面用k-means進(jìn)行聚類分析，程序如下：X=data;Y=X（1:150,2:5）;opts = statset（,Display,/finaF）;idx.ctrs = knieans（X,2/Distance,city,Replicates5/Optionsopts）;表4.1 iris （蜀尾屬植物）聚類結(jié)果表序號(hào)Sepa
