Query regarding k-means clustering in MATLAB

Question

I have a very large amount of data in the form of matrix.I have already clustered it using k-means clustering in MATLAB R2013a. I want the exact coordinates of the centroid

Answer 1

In MATLAB, use

[idx,C] = kmeans(..) 

instead of

idx = kmeans(..) 

As per the documentation:

[idx,C] = kmeans(..) returns the k cluster centroid locations in the k-by-p matrix C.
