%feature("docstring") OT::ARMACoefficients
"Coefficients of an ARMA process (MA or AR part).

Available constructors:
    ARMACoefficients(*size, dimension*)

    ARMACoefficients(*coeffList*)

    ARMACoefficients(*matrixColl*)
   

Parameters
----------
size : int, 
    The number of elements in the list.
dimension : int, 
    The dimension of each element in the list.
coeffList : a list of floats,
    In dimension 1, the list of the coefficients defining the recurrence of the ARMA process (MA or AR part).
matrixColl : a list of :class:`~openturns.SquareMatrix`
    In dimension :math:`d`, the collection of square matrices in :math:`\Rset^d \times \Rset^d` defining the recurrence of the ARMA process (MA or AR part).

Notes
-----

- In the first constructor:

The elements are the null elements (scalar in dimension 1 and the null matrix in upper dimension).

- In the other constructor:

The elements are specified in the constructor.

Examples
--------
Create the coefficients defining the recurrence of an ARMA process:

>>> import openturns as ot
>>> myARCoef = ot.ARMACoefficients([0.4, 0.3, 0.2, 0.1])
>>> myMACoef = ot.ARMACoefficients([0.4, 0.3])"


// ---------------------------------------------------------------------

%feature("docstring") OT::ARMACoefficients::getDimension
"Accessor to the dimension of coefficients in the list.

Returns
-------
dimension : int
    The dimension of elements in the list."

// ---------------------------------------------------------------------

%feature("docstring") OT::ARMACoefficients::add
"Add a new element in the list.

Available usages:
    add(*coeff*)

    add(*squareMat*)

Parameters
----------
coeff : float
    A new scalar coefficient added to the list composed with scalars.
squareMat : :class:`~openturns.SquareMatrix`
    A new element in the list composed with square matrices.

Returns
-------
- In the first usage:

A new list of elements composed with scalars.

- In the second usage:

A new list of elements composed with square matrices.
