triqs::gfs::brzone::mesh_point_t

#include <triqs/mesh/brzone.hpp>

Detailed Description

Mesh point of a triqs::mesh::brzone mesh.

It stores the index \( \mathbf{n} \), data index \( d(\mathbf{n}) \), a pointer to and the hash value of the parent mesh, and the value \( \mathbf{k}^{\mathbf{n}} \).
