WebYou can't use lsim (A,B,C,D,...). You need to use Theme Sys=ss (A,B,C,D); y=lsim (Sys,u,t,X0); UPDATE: You can't arbitrarily set your initial y. Once you get it right, Y0 should be reflected by y=Cx+Du. It looks like lsim (A,B,C,D,...) works too. I started dislike this feature, especially it was not mentioned in the document. Theme Sys=rss (2); WebThe initial condition of the state vector. If X0 is not given, the initial conditions are assumed to be 0. kwargsdict Additional keyword arguments are passed on to the function odeint. See the notes below for more details.
