Depends on what you mean by "code of the tree".
If you want to find classregtree code in your MATLAB install, type 'which classregtree'.
If you want to see pseudo-code for the tree, just display the tree in your command window.
If you want to convert this pseudo-code into a MATLAB script, you'd have to do it yourself. You could start by looking at the DISP method of classregtree (type 'which classregtree/disp'). It's the method that produces the pseudo-code you see in the command window.

This is a fairly simple project. Most of what you need is already in classregtree/disp.
