  Examples

      >>> import numpy.ma as ma
      >>> x = [11.2, -3.973, 0.801, -1.41]
      >>> mask = [0, 0, 0, 1]
      >>> masked_x = ma.masked_array(x, mask)
      >>> masked_x
      masked_array(data=[11.2, -3.973, 0.801, --],
               mask=[False, False, False,  True],
         fill_value=1e+20)
      >>> ma.power(masked_x, 2)
