Hello,
How can I calculate the number of data points of each cluster of K-means ? I found the answer of counter in python, but donot know how to use such kind of commond in MATLAB. I am finding clusters using this code.
[idx,C]
=kmeans(score,3);
figure
gscatter(score(:,1),score(:,2),idx,'bgm')
hold on
plot(C(:,1),C(:,2),'kx', 'MarkerSize',25)
Br,
Haresh Kumar
