Decision Tree

I need to implement a decision tree. Is there any canned
structure or something to help with this? Just seems like it
could get out of hand without pointers and such...

Thanks,

David

The statistics toolbox does have this feature, but I don't know the
details as I never used it. Browse the Mathworks website: there is
plenty of information there.

I saw plottree or something like that that lets me make a
single vector

A = [1 2 2 3 4 5 2 1];

with the parent node's and plot it... but I need to keep
track of more of that (transition probabilities and that
kind of stuff). Is there no built in way to do this?

Thanks

David
