Function ndarray::arr3

pub fn arr3<A: Clone, V: FixedInitializer<Elem = U>, U: FixedInitializer<Elem = A>>(
    xs: &[V]
) -> Array3<A> where
    V: Clone,
    U: Clone, 

Create a three-dimensional array with elements from xs.

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

                [1, 2]]]);

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