Function empty 

pub fn empty<T, D>(dim: D) -> UninitArray<T, D>
where
    T: Element,
    D: Dimension,

Create an uninitialized array.

Analogous to numpy.empty(), but returns a UninitArray that must be explicitly initialized via UninitArray::assume_init.

This prevents accidentally reading uninitialized memory — a key safety improvement over NumPy’s empty().
