Add to ORKGWe discuss the construction of real matrix representations of PT-symmetric operators. We show the limitation of a general recipe presented some time ago for non-Hermitian Hamiltonians with antiunitary symmetry and propose a way to overcome it. Our results agree with earlier ones for a particular case.Instituto de Investigaciones Fisicoquímicas Teóricas y Aplicada
