This is my first attempt at writing Julia code and, to a large extent, a simplified port of the TRIQS/atom_diag library.

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


KeldyshED.jl depends on a few packages. These dependencies can be installed by typing the following commands in Julia's Pkg REPL:

add HDF5
add ArgParse

Some usage examples can be found in the test subdirectory.
