Details

Q_rank_calc(z, p)

domain_sort(X, *Y)

eigAE(A, E)

nearest_idx(lst_1, lst_2=None, metric_pair_dist=None, return_distances=False)

If lst_2 is given, this returns all of the nearest items in lst_2 to lst_1. If not given, this returns all of the nearest elements of lst_1 to itself, ignoring self elements.

if metric_pair_dist is None, use the standard distance on complex plane. This is the fastest.
