Parameters

ham_bml	Hamiltonian in bml format.
over_bml	Overlap in bml format.
hindex	Start and end index for every atom in the system.
hubbardu	Hubbard parameter for every atom.
charges	Charges for every atom.
coulomb_pot_r	Coulombic potential (r contribution)
coulomb_pot_k	Coulombic potential (k contribution)
mdim	Maximum nonzeroes elements per row for every row.
threshold	Threshold value for matrix elements.
