The fisher iris data file in matlab (in case you do not have it). usually it comes with matlab and is called "fisheriris.mat" and can be read without specifying the path of the file.

《MATLAB统计分析与应用》程序与数据有聚类分析、判别分析、主成分分析、因子分析、方差分析、数据拟合、Copula理论等-Statistical analysis and application of "MATLAB" program and data clustering analysis, discriminant analysis, principal component analysis, factor analysis, variance analysis, data fitting

逐步判别分析的主函数 用于分类 [sel,c,c0,re,P]=StepclaassV2(data,[50 50 50],data,10) 输入变量 x为训练集.每行为一个样本，每列为一个变量. Class_x,为训练集的分类情况，一行，为各类样本数量,例如[5 6 9] Test为待分类样本. 输出变量：sel为选择的变量序号，c,c0为拟合出的判别函数.re为对Test的判别结果,P为其后验概率. author 王新 2012.4.8
