I wish I could. Unfortunately, the code I used for my thesis was tightly tied to some proprietary data formats and it also does not run on current versions of Matlab. I you already have the data in MATPOWER format, it would probably be rather straightforward to implement the Implicit Zbus Gauss method, since MATPOWER can easily build the Ybus matrix for you. That's probably the approach I would take if I were you.
