dsimul state space discrete time simulation y=dsimul(sl,u) sl syslin list describing a discrete time linear system u real matrix of appropriate dimension y output of sl Utility function. If [A,B,C,D]=abcd(sl) and x0=sl('X0'), dsimul returns y=C*ltitr(A,B,u,x0)+D*u i.e. the time response of sl to the input u. sl is assumed to be in state space form (syslin list). syslin flts ltitr
