We numerically calculate the quasinormal frequencies of the Klein-Gordon andDirac fields propagating in a two-dimensional asymptotically anti-de Sitterblack hole of the dilaton gravity theory. For the Klein-Gordon field we use theHorowitz-Hubeny method and the asymptotic iteration method for second orderdifferential equations. For the Dirac field we first exploit theHorowitz-Hubeny method. As a second method, instead of using the asymptoticiteration method for second order differential equations, we propose to take asa basis its formulation for coupled systems of first order differentialequations. For the two fields we find that the results that produce the twonumerical methods are consistent. Furthermore for both fields we obtain thattheir quasinormal modes are stable and we compare their quasinormal frequenciesto analyze whether their spectra are isospectral. Finally we discuss the mainresults.
