triqs::gfs::MemoryGf

#include <triqs/gfs/gf/gf.hpp>

Detailed Description

Concept checking that a type behaves like an in-memory Green's function.

A type G models triqs::gfs::MemoryGf if

• it owns a mesh of type M (a triqs::mesh::Mesh) accessible via mesh() and
• a data array accessible via data() that models nda::MemoryArray.

This is the constraint used throughout the Green's function algorithms.

Template Parameters

G	Type to check.
M	Expected mesh type.
