numpy.ma.harden_mask — NumPy v2.3 Manual (original) (raw)

ma.harden_mask(self) = <numpy.ma.core._frommethod object>#

Force the mask to hard, preventing unmasking by assignment.

Whether the mask of a masked array is hard or soft is determined by its hardmask property. harden_mask setshardmask to True (and returns the modified self).
