In this code we show you how to run random forest algorithm classifier in MATLAB :

Code:: TreeObject=TreeBagger(50,TrainData,class,'method ','classification','NVarToSample','all');

First parameter is the number of decision tree to use , TrainData is the training data vector , class is the label for each vector, method parameter is used to differ between regression and classification training. NVarToSample used to set the algorithm to "random forest" .

Now after training , how to use this object for classification :

Code:: [YFIT,scores] = predict(TreeObject,TestVector)

YFIT : label the high fitted class label.
scores : contain the score for each label .
