Solver.evaluate()

Dispatched C++ function(s).

[1] (grid: MeshReFreq, eta: float)
  -> Gf[MeshReFreq, 2]

[2] (grid: MeshReFreq, eta: float, theta: ndarray[complex, 3])
  -> Gf[MeshReFreq, 2]

[1] Evaluate diagonal part of the real-frequency Green’s function on a chosen grid.

Uses the precomputed Nevanlinna factorization.

---

[2] Evaluate the real-frequency Green’s function on a chosen grid using Hardy-function optimization.

---

Parameters:

gridMeshReFreq

Real frequency grid.

etafloat

Lorentzian broadening.

thetandarray[complex, 3]

Hardy-function basis coefficients used to optimize the spectral function.

Returns:

Gf[MeshReFreq, 2]

Real-frequency matrix-valued TRIQS Green’s function on a chosen grid.
