Classes
class	triqs::atom_diag::atom_diag< Complex >
	Lightweight exact diagonalization solver for finite fermionic Hamiltonians. More...
struct	triqs::atom_diag::atom_diag< Complex >::eigensystem_t
	Eigensystem of a single invariant subspace of the Hamiltonian \( H_B \). More...
struct	triqs::atom_diag::atom_diag< Complex >::op_block_mat_t
	Block-matrix representation of an operator \( \hat{O} \) that respects the block structure of the Hamiltonian. More...

Typedefs
using	triqs::atom_diag::indices_t = fundamental_operator_set::indices_t
	Index type used by the fundamental operator set associated with the diagonalization problem.
using	triqs::atom_diag::quantum_number_t = double
	Type used to store quantum-number values. Quantum-number operators are Hermitian, so their eigenvalues are real.
