Does anyone have the source code of the regression decision tree in MATLAB?

I would appreciate it, if anyone can provide me the source code of the regression decision tree in MATLAB with no functions, just the source code.

Thanks

You already have the source code. For example, just do this in MATLAB:

type fitrtree

The code is written in MATLAB itself, so you have it.

Can we give it to you, if you lack the necessary toolbox (stats)? No. That would be illegal.

Thanks for your answer But I need the source code to do some modifications for my research. I don't need the built-in functions. And why it's illegal sine DT is a very old and well known algorithm.

The algoithm MAY be old and well known, but the implementation is theirs, something they have a copyright on. It would certainly be against the rules of this site.

The functions are NOT built-in. They seem to be written in MATLAB itself, at least the one I checked, so you have them already as long as you own the stats toolbox. Modifying such code is just a bad idea, but feel free as long as you own it. And if you don't own that toolbox, it is not at all expensive to buy a toolbox, compared to the time you would need to write that large a set of codes. But since you seem to think the algorithm is so old and well known, then surely you could just write it yourself?
