3.1.52+ indicates that you are using a copy of Octave built from the
Octave development source archive, and that it is out of date.  We
recently made some changes to implement class inheritance that is
intended to be compatible with the way Matlab works.  I'm not sure it
is complete yet, but the recent changes are a move toward full
compatibility.  As a first step, I suggest updating your installation.
