Classification Trees

Binary decision trees for multiclass learning

To interactively grow a classification tree, use the Classification Learner app. For greater flexibility, grow a classification tree using fitctree at the command line. After growing a classification tree, predict labels by passing the tree and new predictor data to predict.
