Hi,
I just theoretically read k-means and did an example..
I had 4, 2d items with their coordinates value, and initially k=2
like
- item variables
- A (5,3)
- B (-1,1)
- C (1,-2)
- D (-3,-2)
I calculated their centroids and then by measuring euclidean dist among arbitrary cluster and centroids, after calculation I got two cluster (A) and (B,C,D)
I am looking at matlab and found kmeans function but how I could implement the following example in matlab, I got messed up..
any hints for first time concept to implement kmeans using matlab using the following example.

Do you mean that you have done it by hand, and you are not sure how to do the same thing with MATLAB?

Is this what you want?
The output does show the two clusters you mention.
X = [ 5 3;
-1 1;
1 -2;
-3 -2];
clusterNumber = kmeans(X,2)
