numpy.ma.MaskedArray.toflex¶
-
MaskedArray.
toflex
()[source]¶ Transforms a masked array into a flexible-type array.
The flexible type array that is returned will have two fields:
- the
_data
field stores the_data
part of the array. - the
_mask
field stores the_mask
part of the array.
Parameters: None
Returns: record : ndarray
A new flexible-type ndarray with two fields: the first element containing a value, the second element containing the corresponding mask boolean. The returned record shape matches self.shape.
Notes
A side-effect of transforming a masked array into a flexible ndarray is that meta information (
fill_value
, …) will be lost.Examples
>>> x = np.ma.array([[1,2,3],[4,5,6],[7,8,9]], mask=[0] + [1,0]*4) >>> print(x) [[1 -- 3] [-- 5 --] [7 -- 9]] >>> print(x.toflex()) [[(1, False) (2, True) (3, False)] [(4, True) (5, False) (6, True)] [(7, False) (8, True) (9, False)]]
