GfImTime.rebinning_tau(*args, **kw)

Dispatched C++ function(s).

[1] (g: Gf[MeshImTime, 2], new_n_tau: int)
  -> Gf[MeshImTime, 2]

Rebin an imaginary-time Green’s function onto a coarser uniform mesh.

The new mesh has new_n_tau points covering the same \([0, \beta]\) interval. Each output point is an average of the input values whose \(\tau\) falls in the corresponding bin.

Parameters:

gGf[MeshImTime, 2]

The imaginary-time Green’s function to rebin.

new_n_tauint

Number of points of the output mesh.

Returns:

Gf[MeshImTime, 2]

A new imaginary-time Green’s function on a mesh of size new_n_tau.
