TAB(A), where A is a vector of polynomial coefficients,
    stabilizes the polynomial with respect to the unit circle;
    roots whose magnitudes are greater than one are reflected
    inside the unit circle.

    Parameters
    ----------
    a : array
        The vector of polynomial coefficients.

    Returns
    -------
    b : array
        The stabilized polynomial.

    Examples
    --------
    Convert a linear-phase filter into a minimum-phase filter with the same
    magnitude response.
