      >>> g = f.expand_dims()

  Parameters: | position: `int`, optional Specify the position amongst the data array axes where the new axis is to be inserted. By default the new axis is inserted at position 0, the slowest varying position. bounds: optional Ignored. i: `bool`, optional If True then update the auxiliary coordinate in place. By default a new auxiliary coordinate is created. In either case, a auxiliary coordinate is returned.
  Returns: | `None`
  Examples: |

      >>> v.expand_dims(2)
      >>> v.expand_dims(-1)
