Package for analytic continuation of many-body Green's functions
Python package to parametrise the multi-channel S-matrix using a pade approximation according to the technique presented in "S.A. Rakityansky P.O.G. Ogunbade. S-matrix parametrization as a way of locating quantum resonances and bound states:multichannel case, 2010".
Contains routines for rational interpolation of functions
