title: Removing outliers from a k-mean cluster
body: <p>I have number of smaller data sets, containing 10 XY coordinates each. I am using Matlab (R2012a)and k-means to obtain a centroid. In some of the clusters (see figure below) I can see some extreme points, beacuse my dataset are as small as they are, one outliner destroys the value of my centroid. Is there a easy way to exlude these points? Supposingly Matlab has a 'exclude outliers' function but I can't see it anywhere in the tool menu..
  Thank you for your help! (and yes I am new to this:-)</p>
