In Matlab, upon running the function fitrtree, a regression tree is returned. When the tree is constructed it partitions the sample space in small hyper-rectangles using binary decision rules. When the tree stops growing, each leaf in the tree will be satisfied by at-least the MinLeaf number of samples from the training data. I want to obtain which samples of my training data belong to which leaf (or node) of the tree.

I also have the same question, did you happen to find the answer? I would like to be able to fit an appropriate distribution to the errors at each node, or at least sample from the errors at each node.

Thank you,

Greg
