qhull hyperplane normals

Subject: qhull hyperplane normals

Hello,
Can I use the output option {'n'} of the qhull algorithm in order to output the hyperplane normals with offsets in Matlab.

Thanks,
Dimitar

I don't think so, but one you've found the vertices of the polytope using convhulln() you can then use the following FEX tool to get the normals/offsets
