Generalised Fractional Indexes Approximation with Application to Discrete-Time Generalised Weyl Symbol Computation

摘要

Dynamical, linear discrete-time system can be described by finite set of coefficients of difference equations or state space model. The set define dynamics of the linear time-invariant system for all times k ∈ Z (infinite time horizon). In contradistinction the description of discrete-time linear time-varying systems requires in general definition of an infinite number of coefficients.
