ISODATA法分类IRIS数据集，压缩包中包括两个.m文件，运行provaisodata_4D.m可直接分类。或者通过isodata_4D.m设置参数也可以得到结果。程序有详细注释，很容易懂。最后结果既有文字描述，也有图形输出。(ISODATA classification method IRIS data set, compressed package includes two. M files, run provaisodata_4D.m direct classification. Or set the parameters by isodata_4D.m can get results. Procedures detailed notes, it is easy to understand. Final results of both the written description, there are graphical output.)
