The initial public version of this package was a simplified Julia port of the TRIQS/atom_diag library, but has since acquired a few new features.

Special thanks to Joseph Kleinhenz for reviewing my code, as well as for writing the Keldysh.jl library, which KeldyshED.jl depends on.

Usage

KeldyshED.jl can be installed by typing the following command in Julia's Pkg REPL:

pkg> add KeldyshED

Some usage examples can be found in the test subdirectory. An API reference is available at the documentation website.
