Follow-up Comment #4, bug #49774 (project octave):

I've only been looking at this today, but that said, I'm not sure if simplify
is not extraneous.  Small experimentation with qhull gets me a set of random
points in a square with 

rbox 50 D2 | qconvex G > a

In this case the interior points are not displayed in geomview.  To display
the interior and as I understand it simplified points we need to run qconvex
Ga instead of G.  This shows all the points in the interior of the convex hull
and the hull itself.  My question is if the default behaviour in qhull is to
make the convex hull and ignore the interior points, what is simplified by
simplify? 

That said, I'm sure mathworks doesn't put things like simplify in their code
without reason.
