Auxiliary Green’s function helpers: mesh-conversion setters, Pade continuation, imaginary-time tools, and symmetry predicates.

Functions

enforce_discontinuity	Enforce a prescribed jump at \(\tau = 0\) for a Legendre Green's function.
is_gf_hermitian	Test whether a Green's function satisfies the hermitian symmetry up to a tolerance \(\epsilon\).
is_gf_real_in_tau	Test whether a Matsubara Green's function corresponds to a real imaginary-time Green's function.
rebinning_tau	Rebin an imaginary-time Green's function onto a coarser uniform mesh.
set_from_imfreq	Project a Matsubara Green's function onto the Legendre basis of the output.
set_from_imtime	Project an imaginary-time Green's function onto the Legendre basis of the output.
set_from_legendre	Project a Legendre Green's function onto the Matsubara mesh of the output.
set_from_pade	Analytically continue a Matsubara Green's function to the real-frequency axis using a Pade approximant.
tau_L2_norm	Calculate the \(L^2\) norm of a DLR Green's function.
