# numpy.ma.asanyarray

`numpy.ma.``asanyarray`(a, dtype=None)

  Convert the input to a masked array, conserving subclasses.

  If a is a subclass of MaskedArray, its class is conserved. No copy is performed if the input is already an ndarray.

  Parameters : | a : array_like Input data, in any form that can be converted to an array. dtype : dtype, optional By default, the data-type is inferred from the input data. order : {‘C’, ‘F’}, optional Whether to use row-major (‘C’) or column-major (‘FORTRAN’) memory representation. Default is ‘C’.
  Returns : | out : MaskedArray MaskedArray interpretation of a.

  `asarray`
    Similar to asanyarray, but does not conserve subclass.

  Examples

      >>> x = np.arange(10.).reshape(2, 5)
      >>> x
      array([[ 0.,  1.,  2.,  3.,  4.],
             [ 5.,  6.,  7.,  8.,  9.]])
      >>> np.ma.asanyarray(x)
      masked_array(data =
       [[ 0.  1.  2.  3.  4.]
       [ 5.  6.  7.  8.  9.]],
                   mask =
       False,
             fill_value = 1e+20)
      >>> type(np.ma.asanyarray(x))
      <class 'numpy.ma.core.MaskedArray'>
