triqs.mesh.mesh_point.MeshPoint

class triqs.mesh.mesh_point.MeshPoint(index, data_index, mesh_hash, value=None, weight=None)

Bases: object

A single point on a TRIQS mesh.

A mesh point bundles its mesh-native index \(n\), its data index \(d\), the hash of the parent mesh and – for most meshes – the physical value at the point.

Arithmetic and casting are forwarded to value, so a MeshPoint can be used in numerical expressions in place of its underlying scalar / vector.

Parameters:

indexobject

Mesh-native index \(n\).

data_indexint

Data index \(d\).

mesh_hashint

Hash of the parent mesh.

valueobject, optional

Physical value at the point. Defaults to None.

weightobject, optional

Optional integration weight associated with the point. Defaults to None.

Attributes

real	Real part of value.
imag	Imaginary part of value.

index	(object) Mesh-native index \(n\).
data_index	(int) Data index \(d\).
mesh_hash	(int) Hash of the parent mesh
value	(object) Physical value or None.
weight	(object) Integration weight or None.

Methods

__call__(*args, **kw)

Forward the call to value.
