triqs::gfs::dlr_imfreq::mesh_point_t

#include <triqs/mesh/dlr_imfreq.hpp>

Detailed Description

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

It inherits from triqs::mesh::matsubara_freq and in addition to the Matsubara index \( n_l \), the inverse temperature \( \beta \) and the particle statistics, it also stores the data index \( d \) and the hash value of the parent mesh.
