Hi Daniel,

As I said in my other email, it does work, it just needs at least one 
symbolic input.

But Octave's warning here is misleading ("not yet been implemented") so 
I've proposed a patch [1] and CC'd the octave-maintainers mailing list.

[1] https://savannah.gnu.org/patch/?9238

With that patch, you would see something more helpful:

>> dsolve
warning: 'dsolve' is a method of class 'sym'; it must be called
with a 'sym' argument (see 'help @sym/dsolve').

best,
Colin
