MeshImFreq.to_data_index()

Dispatched C++ function(s).

[1] (n: int)
  -> int

[2] (iw: MatsubaraFreq)
  -> int

[1] Map a Matsubara index \(n \in \{ n_{\text{min}}, \dots, n_{\text{max}} \}\) to its corresponding data index \(d(n)\).

---

[2] Map a Matsubara frequency \(i\omega_n\) to its data index \(d(i\omega_n)\).

---

Parameters:

nint

Matsubara index \(n\) to map.

iwMatsubaraFreq

Matsubara frequency to map.

Returns:

[1]int

Data index \(d(n) = n - n_{\text{min}}\).

[2]int

Data index \(d(i\omega_n) = n - n_{\text{min}}\).
