Just copy and paste when I was trying to understand what was going on.

It doesn't seem to work though. Please test it with my example and if it works 
I will have to look further on the qhull libraries (I think I have the 
latest).

This would be perfect. However I still don't understand how the non-simplex 
facets with non triangulated output will be imported to octave. We would need 
a matrix with as many columns as the largest number of vertices in this facet 
and define vertex 0 as non-existant, or something like...

Waiting to test the new convhulln....
