Running "demo isonormal 1" in Octave and in Matlab (see bug #55481), the direction of the automatically calculated normals is different in Matlab and in Octave.
While in Matlab all normals seem to point towards the center (the origin or the barycenter of the patch?), they point in different directions in Octave (determined by the order of the vertices in each face).
This is not a bug in isonormal but in the algorithm that is used to automatically calculate the normals.
