Thank you for your reply.
Formally, d(x,y)=|x or y|. This is not a metric distance function but
gave me good result in hierarchical clustering (Matlab linkage function,
bottom-up) so I just wanted to test that using a top-down approach in
larger scale.

You can't define distance this way, relative to something changing or not
when a point is added. What is "closest" here? Just trying to save you
trouble down the road as I am not sure this will make meaningful results,
even if you get something to run.
