docs: Returns an array of length size and type dtype that is everywhere 0,
    except in the indices listed in sequence pos.
  
    :param pos:   A single integer or sequence of integers that specify
           the position of ones to be set.
    :param size:  The total size of the array to be returned.
    :param dtype: The element type (compatible with NumPy array())
           of the array to be returned.
    :returns: An array of length size and element type dtype.
