# numpy.ma.filled

ma.filled(a, fill_value=None)

  Return input as an `ndarray`, with masked values replaced by fill_value.

  If a is not a `MaskedArray`, a itself is returned. If a is a `MaskedArray` with no masked values, then `a.data` 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.

      >>> import numpy as np
      >>> import numpy.ma as ma
      >>> x = 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],
