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=999999)
>>> ma.getdata(a)
array([[1, 2],
       [3, 4]])
Equivalently use the MaskedArray data attribute.
>>> a.data
array([[1, 2],
       [3, 4]])
