numpy.ma.all#

ma.all(self, axis=None, out=None, keepdims=<no value>) = <numpy.ma.core._frommethod object>#

Returns True if all elements evaluate to True.

The output array is masked where all the values along the given axis are masked: if the output would have been a scalar and that all the values are masked, then the output is masked.
