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。
