Function arr3

pub fn arr3<A, V, U>(xs: &[V]) -> ArrayBase<OwnedRepr<A>, Dim<[usize; 3]>>
where
    A: Clone,
    V: FixedInitializer<Elem = U> + Clone,
    U: FixedInitializer<Elem = A> + Clone,

Create a three-dimensional array with elements from xs.

Panics if the slices are not all of the same length.

               [[9, 0],
                [1, 2]]]);

    a.shape() == [3, 2, 2]
