use of convhulln to calculate total area and volume

[Fred Touwslager]

According to the documentation of qhull I should be able to compute the
volume of a convex hull in 3 dimensions by using the option: s FA.
Using the qhull program in a Cygwin environment this works. 
 
However, using convhulln(P,{"s","FA"}) in Octave gives me only the index
vector to the points of the enclosing convex hull, and not the volume.
 
In MatLab the use is: [l v] = convhull(P);
 
But I'm not able to get this working in Octave 3.0.3 (under Windows XP).
 
Anybody any Idea what I'm doing wrong?
 

Kind regards,
