What is the best matlab data structure to represent a decision tree?

I want to be able to access the level of the tree and the number of nodes and the information of the nodes after a split. What is the best data structure to use?

Please explain in some detail and in simple terms. I am new to matlab.

Hi Kunal,

MATLAB offers several resources more creating data structures such as a tree. Some useful resources I can suggest are:

• Structures: http://www.mathworks.com/help/matlab/ref/struct.html
• Cell arrays: http://www.mathworks.com/help/matlab/cell-arrays.html
• Classes: http://www.mathworks.com/help/matlab/ref/classdef.html

I would also suggest taking a look at the MathWorks documentation for object-oriented programming in MATLAB: http://www.mathworks.com/help/matlab/object-oriented-programming.html

I'm partial to the ones included in Statistics and Machine Learning Toolbox.

It seems the link is dead (for newer releases) due to the split into separate classification trees and regression trees pages.
