11.1.7.6.9.1.4. numpy.ma.MaskedArray.unshare_mask¶

MaskedArray.unshare_mask()[source]¶

Copy the mask and set the sharedmask flag to False.

Whether the mask is shared between masked arrays can be seen from the sharedmask property. unshare_mask ensures the mask is not shared. A copy of the mask is only made if it was shared.
