# numpy.ma.allequal

ma.allequal(a, b, fill_value=True)

  Return True if all entries of a and b are equal, using fill_value as a truth value where either or both are masked.

  Parameters
    a, b array_like

      Input arrays to compare.

    fill_value bool, optional

      Whether masked values in a or b are considered equal (True) or not (False).

  Returns
    y bool

      Returns True if the two arrays are equal within the given tolerance, False otherwise. If either array contains NaN, then False is returned.

  Examples

      >>> a = np.ma.array([1e10, 1e-7, 42.0], mask=[0, 0, 1])
      >>> a
      masked_array(data=[10000000000.0, 1e-07, --],
                   mask=[False, False,  True],
             fill_value=1e+20)

      >>> b = np.array([1e10, 1e-7, -42.0])
      >>> b
      array([  1.00000000e+10,   1.00000000e-07,  -4.20000000e+01])
      >>> np.ma.allequal(a, b, fill_value=False)
      False
      >>> np.ma.allequal(a, b)
      True
