初步学习之FCM

先贴代码：

data = rand(100,2);
       [center,U,obj_fcn] = fcm(data,2);
      plot(data(:,1), data(:,2),'o');
      hold on;
       maxU = max(U);
     % Find the data points with highest grade of membership in cluster 1
      index1 = find(U(1,:) == maxU);
   % Find the data points with highest grade of membership in cluster 2
      index2 = find(U(2,:) == maxU);          line(data(index1,1),data(index1,2),'marker','*','color','g');
      line(data(index2,1),data(index2,2),'marker','*','color','r');
       Plot the cluster centers
       plot([center([1 2],1)],[center([1 2],2)],'*','color','k')
      hold off;

这是help FCM函数得到的例子。
