Calculate the \(L^2\) norm of a DLR Green’s function.

Parameters:

gGf[MeshDLR, 0], Gf[MeshDLR, 2], Gf[MeshDLRImFreq, 0], Gf[MeshDLRImFreq, 2], Gf[MeshDLRImTime, 0], Gf[MeshDLRImTime, 2], BlockGf[MeshDLR, 0], BlockGf[MeshDLR, 2], BlockGf[MeshDLRImFreq, 0], BlockGf[MeshDLRImFreq, 2], BlockGf[MeshDLRImTime, 0], BlockGf[MeshDLRImTime, 2]

A Green’s function on any DLR mesh.

Returns:

[1, 3, 5]float

The \(L^2\) norm of the input Green’s function, either as a scalar (if target rank is 0) or as an array of norms for each element in the target domain (if target rank is greater than 0).

[2, 4, 6]ndarray[float, 2]

The \(L^2\) norm of the input Green’s function, either as a scalar (if target rank is 0) or as an array of norms for each element in the target domain (if target rank is greater than 0).

[7, 9, 11][float]

The \(L^2\) norm of the input Green’s function, either as a scalar (if target rank is 0) or as an array of norms for each element in the target domain (if target rank is greater than 0).

[8, 10, 12][ndarray[float, 2]]

The \(L^2\) norm of the input Green’s function, either as a scalar (if target rank is 0) or as an array of norms for each element in the target domain (if target rank is greater than 0).
