Another bug in lsim is that you have to specify a time vector even though it
says you don't have to.

-- Function File: lsim (SYS, U)
 -- Function File: lsim (SYS1, SYS2, ..., SYSN, U)
 -- Function File: lsim (SYS1, 'STYLE1', ..., SYSN, 'STYLEN', U)

lsim(q,ones(101,1))

Thanks for this.

I started to fix it and run into a problem.

How do we decide on the total time to run the simulation?

@GoSim

 If you don't  specify a time vector what would you expect lsim to do?

Matlab requires a t  

So i think our documentation is just lacking.
