numpy.ma.getdata#

ma.getdata(a, subok=True)[source]#

Return the data of a masked array as an ndarray.

Return the data of a (if any) as an ndarray if a is a MaskedArray, else return a as a ndarray or subclass (depending on subok) if not.

Parameters:

aarray_like: Input MaskedArray, alternatively a ndarray or a subclass thereof.
subokbool: Whether to force the output to be a pure ndarray (False) or to return a subclass of ndarray if appropriate (True, default).

See also

getmask: Return the mask of a masked array, or nomask.
getmaskarray: Return the mask of a masked array, or full array of False.

Examples

>>> import numpy.ma as ma
>>> a = ma.masked_equal([[1,2],[3,4]], 2)
>>> a
masked_array(
  data=[[1, --],
        [3, 4]],
  mask=[[False,  True],
        [False, False]],
  fill_value=2)
>>> ma.getdata(a)
array([[1, 2],
       [3, 4]])

Equivalently use the MaskedArray data attribute.

>>> a.data
array([[1, 2],
       [3, 4]])
