# numpy.ma.MaskedArray.all

method

ma.MaskedArray.all(axis=None, out=None, keepdims=<no value>)

  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.
