numpy.ma.MaskedArray.ids

MaskedArray.ids() [source]

Return the addresses of the data and mask areas.

Parameters: None

Examples

>>> x = np.ma.array([1, 2, 3], mask=[0, 1, 1])
>>> x.ids()
(166670640, 166659832)

If the array has no mask, the address of nomask is returned. This address is typically not close to the data in memory:

>>> x = np.ma.array([1, 2, 3])
>>> x.ids()
(166691080, 3083169284L)
