Return the common filling value of two masked arrays, if any.

If a.fill_value == b.fill_value, return the fill value, otherwise return None.

Parameters

a, bMaskedArray

The masked arrays for which to compare fill values.

Returns

fill_valuescalar or None

The common fill value, or None.

Examples

>>> x = np.ma.array([0, 1.], fill_value=3)
>>> y = np.ma.array([0, 1.], fill_value=3)
>>> np.ma.common_fill_value(x, y)
