simulink - Time driven simulation backwards steps -


i looking alternative simulink allow control stepping mechanism. same concern raised in question, simulink not allow backwards stepping, complex systems x(t,u) "changing variables" (t <- -t) requires weeks of work, cannot controlled (u) correctly due interdependance between past states , present decisions (u=f(x(s)),s<=t).

conceptually, trick consists in manually storing previous states in memory : simulink user, difficult , error prone, whereas stepping backwards in time simple , fit nicely in simulink, developer's point of view.
