> the constructor     public ArrayFieldVector(T[] v1, ArrayFieldVector<T> v2) {
>  ... 
> }
> takes an ArrayFieldVector.
> but the same can be easier archieved with this 
>     public ArrayFieldVector(T[] v1, FieldVector<T> v2) {
>         this(v1, v2 == null ? null : v2.getData());
>     }
> this goes for all other constructors...
> P.S. I donk know if copying the data in getData is an issue ... for this the named constructor may make sense...
