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

numpy.ma. mean(self, axis=None, dtype=None, out=None, keepdims=<class numpy._globals._NoValue at 0x40b9ccec>) = <numpy.ma.core._frommethod instance>¶

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.

Examples

a = np.ma.array([1,2,3], mask=[False, False, True]) a masked_array(data = [1 2 --], mask = [False False True], fill_value = 999999) a.mean() 1.5
