title: Hamming distance in k-means clustering
body: <p>I want to use the hamming distance in kmeans clustering in Matlab, but I get an error saying that my data must be binary. </p>
  
  <p>Is there anyway around this? The data matrix that I use can't be binary (it has a physical interpretation that must allow for values 0,1,2,3) but it's important that I use the Hamming distance.</p>
