No, dim_vector is a separate class, not derived from Array<T>.  Look
at liboctave/dim-vector.h to see the definition and available methods.

Yes, the Array classes have some special cases for 2 and 3 dimensional
objects just for convenience as those are the most common cases.

All objects in Octave should have at least two dimensions.
