hi, I found the following code of matlab in this link http://www.ideal.ece.utexas.edu/~gjun/ee379k/html/clustering/hac/page2.html

load c.txt;
P=pdist(c,'euclidean');
Z=linkage(P,'single');
T=cluster(Z,'MaxClust',2);
plot_clusters(c,T);

I tried it with my data , it is working except the last function , it is what I looked for , this function plot each cluster with different color

how can find it? please, i badly need it in my work.

thanks

huda, you have not formatted the code in this post.

@huda: Thanks for your apology. Apologies are not useful here, but improving your style to ask question is. Most of all this would be an advantage for me, the forum and last but not least for yourself.

Many thanks,

I got it and run it. But what if I ran the above code on my data but my data is not 2D , my data is n*n similarity matrix, and I ran the above function on my data

P=pdist(c,'euclidean');
Z=linkage(P,'single');
T=cluster(Z,'MaxClust',2);

and got T the label for each observations (n). Now , i want to use plot_clusters with this case . if plot_clusters is not working with this case, are there alternative way to see the clusters graphically.

thanks
