numpy.ma.mean¶

ma.mean(self, axis=None, dtype=None, out=None, keepdims=<no value>) = <numpy.ma.core._frommethod object>¶

Returns the average of the array elements along given axis.

Masked entries are ignored, and result elements which are not finite will be masked.

Refer to numpy.mean for full documentation.

       fill_value=999999)
>>> a.mean()
