Hi,
I am currently working with the method prune which is defined in the ClassificationTree class in Matlab 2013
I would like to to know which pruning algorithm is being used (Cost Complexity Pruning, Rule Post Pruning, Pessimist Error Pruning, Error Bases Pruning,....)
Does anyone know which algorithm Matlab uses?
Thanks in advance.

ClassificationTree is based on Breiman, L., J. Friedman, R. Olshen, and C. Stone, Classification and Regression Trees, and uses cost-complexity pruning described in that book.
