numpy.ma.masked_array.unshare_mask — NumPy v1.13 Manual (original) (raw)

masked_array. 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.
