说明：  本程序实现对多进制PSK数字调制系统的仿真。程序运行需要几分钟，请耐心等待(this program right M-ary PSK modulation system simulation. Procedures required for the operation of a few minutes, please wait patiently)

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.)

MATLAB structures provide a way to collect arrays of different types and sizes in a single array. The following codes show how this can be made for problem1.m. One of the most interesting features is that the argument passing to functions is simplified. MATLAB codes for Finite Element Analysis problem1.m antonio ferreira 2008
