.. _e2i_fit: :math:`\chi^2` Fit ########################### The module :f:mod:`E2I_BATH_FIT` includes a function to extend the bath optimisation to the case of multiple user baths corresponding to each inequivalent impurity. Where possible the optimization is parallel with respect to the impurities. See the module :f:mod:`ED_BATH_FIT` for further information about the fit for a single impurity. .. preferred-crossrefs:: :sf_linalg/operator(.x.): f/sf_sparse_array_csr/operator(.x.) .. f:automodule:: e2i_bath_fit
