Abstract. A sufficient condition for nonlinear sampling system asymptotic stability at large is obtained. Places of system matrix columns depend on phase co-ordinate vector. It is demonstrated possibility to obtain the less hard sufficient stability condition with phase co-ordinate scale changing. Sometimes it is possible to obtain the necessary and sufficient stability condition.
Keywords: asymptotic stability, nonlinear discrete system, a sufficient condition of stability.
