Masked values of 1 exclude the corresponding element from
any computation.
Construction:
x = array(data, dtype=None, copy=True, order=False,
mask = nomask, fill_value=None)
If copy=False, every effort is made not to copy the data:
If data is a MaskedArray, and argument mask=nomask,
then the candidate data is data.data and the
mask used is data.mask. If data is a numeric array,
it is used as the candidate raw data.
If dtype is not None and
is != data.dtype.char then a data copy is required.
Otherwise, the candidate is used.
If a data copy is required, raw data stored is the result of:
numeric.array(data, dtype=dtype.char, copy=copy)
If mask is nomask there are no masked values. Otherwise mask must
be convertible to an array of booleans with the same shape as x.
fill_value is used to fill in masked values when necessary,
such as when printing and in method/function filled().
The fill_value is not used for computation within this module.

ƒ ƒ S( s¥ Returns true if all components of a and b are equal
subject to given tolerances.
If fill_value is 1, masked values considered equal.
If fill_value is 0, masked values considered unequal.
The relative error rtol should be positive and << 1.0
The absolute error atol comes into play for those elements
of b that are very small or zero; it says how small a must be also.
