numpy.ma.filled#
- ma.filled(a, fill_value=None)[source]#
Return input as an array with masked data replaced by a fill value.
If a is not a
MaskedArray
, a itself is returned. If a is aMaskedArray
and fill_value is None, fill_value is set toa.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
