There is a package in Octave [1] that allows solving PDEs in 1- 2- and 3D with
a combination of Finite Elements and Finite Volume methods.
This package was initially intended to be compatible with Matlab's PDEtoolbox
(which was 2d only).
As far as I know, though, the PDEtoolbox was discontinued when Comsol decided
to make its Multiphysics simulation environment independent of Matlab (the
process also included a lawsuit between the two companies [2]).
At the moment I think to have a pde solver in Matlab one needs to acquire both
a license for Matlab AND Comsol Multiphysics [3].
So, as far as I can tell, it's more like Octave does have a PDE solver at the
moment while Matlab doesn't.

P.S. There are actually more 3rd party PDE solvers available that work with
both Octave and Matlab,
for example [4] and [5] to name but a few.
