Types

ACTest.AbstractFunction — Type
AbstractFunction

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

ACTest.SpectralFunction — Type
SpectralFunction

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

Members

  • mesh -> Real frequency mesh, ω.
  • image -> Spectral function, A(ω).
ACTest.GreenFunction — Type
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.
