Expand description

A minimal pole representation G(z) = Σ_j A_j / (z - ξ_j) + C.

Fields§

§pole_location: Vec<Complex<f64>>

Pole locations ξ_j, sorted by real part.

§pole_weight: TypedTensor<Complex<f64>>

Pole weights A_j, shape [M, ...].

§constant: Vec<Complex<f64>>

Constant term C, one entry per channel (column-major).

§h_k: TypedTensor<Complex<f64>>

Moments (contour integrals) h_k, shape [K, ...].

§esprit: Esprit

The ESPRIT approximation of h_k.

§n0: usize

n0 used for the contour.

§err_max: Option<f64>

Precision of the first approximation of the Matsubara data (mini_pole only).
