AbstractFunction

An abstract type representing the general functions. It is used to build the internal type system.

SpectralFunction

Mutable struct. It represents the spectral function A(ω).

Members

• mesh -> Real frequency mesh, ω.
• image -> Spectral function, A(ω).

GreenFunction

Mutable struct. It represents the Green's function G(iωₙ) or G(τ).

Members

• grid -> Imaginary axis grid, ωₙ or τ.
• green -> Green's function, G(iωₙ) or G(τ).
• error -> Standard deviation of the Green's function, σ.
