`numpy.ma.core:ids`

Signature

def ids ( self )

Return the addresses of the data and mask areas.

import numpy as np
x = np.ma.array([1, 2, 3], mask=[0, 1, 1])
x.ids()

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()
