It just allocates space, leaving spurious content in the array. This
is OK if you are later going to assign each element. If you want the
entries initialised you can use zeros() or ones().

Return a new array of shape (d1,...,dn) and given type with all its
    entries uninitialized. This can be faster than zeros.
