triqs::gfs::make_real_in_tau
#include <triqs/gfs.hpp>
Synopsis
template<typename G>typename G::regular_type make_real_in_tau (G const & g)
Symmetrize a Matsubara Green function object such that the associated imaginary-time propagator is fully real-valued. The following transformation is performed \(G[i\omega](...) \rightarrow \frac{1}{2} ( G[i\omega](...) + conj(G[-i\omega](...)) )\)
Template parameters
The Green function type
Parameters
g The Green function object to symmetrize
Returns
The symmetrized Green function object
