numpy.ma.MaskedArray.ids — NumPy v1.13 Manual (original) (raw)

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)
