Hi,

Thanks for your report. Actually ML doc does not mention the order in which vertices are returned so it is not clear that Octave should reorder vertices to follow this behavior.
I leave "Matlab compatibility" as item group for the time being, but we don't generally consider those undocumented behaviors as hard constraints.
On the other hand if you provide us with a practical case in which the order of vertices is critical then we could decide to change this in Octave. Reordering on the basis of the value of the rotational can be vectorized and the fast.

Attached script del.m reports the orientation of the triangles in a delaunay triangulation.

On matlab it will always report "clockwise" for all triangles,
on octave the orientaion of the triangles seems to be random.
