Hello. I agree that the symbolic toolbox could do with some more
documentation. You'll find some in the Wiki
http://wiki.octave.org/wiki.pl?OctaveForgeGNCIntro
which I plan to add to shortly. (Adding in particular a mention of the
need to initialize the toolbox by calling `symbols', as you pointed
out.)
