Regression tree and AIC

Hello.

I have 20 predictors and some of them are correlated. I also have to fit a regression tree and choose best predictors using AIC. I used fitrtree, but I don't know how to calculate AIC. Could someone please help?

The default optimizer is Bayesian, could you extract the BIC & rescale it to AIC?

How can I do that?

I am sorry, this is new to me :)
