After i perform kmeans algorithm of matlab , i get the number of the desired clusters. Now if i want to see the data points of each cluster , how will i proceed. Is there any command in matlab that would help me get that. Any suggestions would be really helpful. Thank You

K = 4 ; % groups
N = 5000 ;
x = rand(N,1) ;
y = rand(N,1) ;
% apply kmeans
idx = kmeans([x,y],K) ;
% get each cluster
data = cell(K,1) ;
figure
hold on
for i = 1:K
data{i} = [x(idx==i),y(idx==i)] ;
plot(x(idx==i),y(idx==i),'.')
end

Since we can't even visualize 275 dimensions, why do you think you have 6 centroids? What leads you to that conclusion/guess? Do you have any screenshots to explain that?

I am assuming 6 clusters. But I am working on testing with different k number and then compute sillhouette score to see which number to pick.
