Linear Rational Disc Stage

class iirrational.RDF.RationalDiscFilter(_args=None, copy=None, lightweight=True, **kwargs)

matched_pairs_clear(Q_rank_cutoff=0.5)

Match unique closest pairs, if they are within a bandwidth of 0Hz, then they are ignored

Nonlinear flexible parameterization fitting

class iirrational.MRF.MultiReprFilter(_args=None, copy=None, lightweight=True, **kwargs)

optimize_NM(bootstrap=True, residuals_type=None, **kwargs)

Uses Nelder-Mead with a simplex that is bootstrapped from the svd of the jacobian. This gives particularly good initial directions to check
