Szukana fraza: [Abstract = "The Weierstrass\-Kronecker theorem on the decomposition of the regular pencil is extended to fractional descriptor continuous\-time linear systems described by the Caputo\-Fabrizio derivative. A method for computing solutions of continuous\-time systems is presented. Necessary and sufficient conditions for the positivity and stability of these systems are established. The discussion is illustrated with a numerical example."]
