用C#实现k均值聚类算法
                                      
k均值算法是模式识别的聚分类问题,这是用C#实现其算法
以下是程序源代码:

namespace KMean_win
{
     ///
     /// Form1 的摘要说明。
     ///
     public class Form1 :
     {
         ///
         /// 必需的设计器变量。
         ///
         private = null;
         private static int k = 2;                          //类数,此例题为2类
         private static int total = 20;                      //点个数
         private int test = 0;
         private PointF[] unknown = new PointF[total];  //点数组
         private int[] type = new int[total];           //每个点暂时的类
         public PointF[] z = new PointF[k];                 //保存新的聚类中心
         public PointF[] z0 = new PointF[k];                //保存上一次的聚类中心
         private PointF sum;
         private int temp = 0;
         private textBox1;
         private int l = 0;          //迭代次数
//构造函数,初始化
         public Form1()
         {
              unknown[0]=new Point(0,0);
              unknown[1]=new Point(1,0);
              unknown[2]=new Point(0,1);
              unknown[3]=new Point(1,1);
              unknown[4]=new Point(2,1);
              unknown[5]=new Point(1,2);
              unknown[6]=ne
