How do I declare a symbolic matrix in Octave?

Question

In MatLab, you can declare symbols pretty easily:

syms a,b
mat = [a,b]

I'm getting an error, however, when I try to replicate this in Octave. This is the code I'm using:

> symbols
> a = sym("a")
a =

a
> b = sym("b")
b =

b
> mat = [a,b]

It looks like you might need the symbolic toolbox package, reference here.
