C++ documentation

The TRIQS library provides a generic container gf and its views gf_view and gf_const_view, to store and manipulate various Green functions on various meshes, e.g.:

• Matsubara frequency(ies),
• Matsubara time(s),
• real time(s),
• real frequency(ies),
• Legendre representation.
• Block of other green functions.
• Cartesian product of green functions.

Various free functions are also provided to handle transformations between various representation of a Green function, such as Fourier transforms.
