Has anyone used
clasregtree
function to build a tree with numerical responses (Y)? If yes then any idea how the means (Y bar) at each leaf (terminal nodes) is calculated?
Thanks

Have you tried reading the documentation?
doc classregtree
or looking at the code?
edit classregtree

Attached is the function, actually classregtree is a class which I have no idea how to edit or get the intermediate results. If you look at line 746, ybar is calculated. Any idea on how to obtain that?

I suggest you take a look at this page about debugging MATLAB.
Where you first call classregtree, you should be able to set a breakpoint, and then step through the function line-by-line to see the values all variables during the calculation.
