dask.array.ma.filled

dask.array.ma.filled(a, fill_value=None)[source]

Return input as an array with masked data replaced by a fill value.

This docstring was copied from numpy.ma.filled.

Some inconsistencies with the Dask version may exist.

If a is not a MaskedArray, a itself is returned. If a is a MaskedArray and fill_value is None, fill_value is set to a.fill_value.

Parameters
aMaskedArray or array_like

An input object.

fill_valuearray_like, optional.

Can be scalar or non-scalar. If non-scalar, the resulting filled array should be broadcastable over input array. Default is None.

Returns
andarray

The filled array.

>>> x = np.ma.array(np.arange(9).reshape(3, 3), mask=[[1, 0, 0],  
...                                                   [1, 0, 0],
...                                                   [0, 0, 0]])
>>> x.filled()  
array([[999999,      1,      2],
       [999999,      4,      5],
       [     6,      7,      8]])
>>> x.filled(fill_value=333)  
array([[333,   1,   2],
       [333,   4,   5],
       [  6,   7,   8]])
>>> x.filled(fill_value=np.arange(3))  
array([[0, 1, 2],
