I think the
matlabdocumentation related to this is very clear. However your question about... use a kd-tree for efficient distance computationsis not quite so clear.I mainly mean who cares, but if you do; then do some timings between alternatives.
Anyway the question with ‘rules’-parameter is way much more complicated, than just finding out some simple
kd-treeusage. So please really try to time your operations first and if they are not sufficient somehow, I’ll surely be able to fine tune them for you then!
