# numpy.ma.filled

ma.filled(a, fill_value=None)

  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 a `MaskedArray` and fill_value is None, fill_value is set to `a.fill_value`.

  Parameters
    a MaskedArray or array_like

      An input object.

    fill_value array_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
    a ndarray

      The filled array.

  Examples

      >>> 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],
             [0, 4, 5],
             [6, 7, 8]])
