K- Means clustering problem

Hello Everyone,

I have a small problem with clustering. I don't know if someone can help me with, i want to plot the graph of points and the centroids when i am using k-means clustering on the vector y = [ 2 4 5 6 7 8 1 1 3 4] and k=3 i am using the following commands:

n= [1:10]
y = [ 2 4 5 6 7 8 1 1 3 4]
plot(n, y, '*')
 --those are the points i want to partition between the 3 clusters--

[p o]=kmeans(y,3)
plot(y(1,p==1),'r.')
plot(y(1,p==2),'b.')
plot(o(1,:),o(2,:),'kx')
plot(o(1,:),o(2,:),'ko')

Try "help hold" to see how to make plotting commands stop overwriting previous figure contents.
