dft_tools/test/triqs/gfs/gf_positive_and_negative_matsubara.cpp
tayral 82a6d21939 Fixed computation of density for full matsub mesh
-> Previously, calculation was implicitly assuming a mesh with only positive matsubara frequencies.
-> Added corresponding test
-> Also added test of density calculation with or without correct tail.
