We present an exact diagonalization C++ template library (EDLib) for solving quantum electron models, including the single-band finite Hubbard cluster and the multi-orbital impurity Anderson model. The observables that can be computed using EDLib are single particle Green’s functions and spin–spin correlation functions. This code provides three different types of Hamiltonian matrix storage that can be chosen based on the model.
