Obtain ALL output data from 'lsim' comman whe using an uncertain system

I have an uncertain system 'clp' of 7 inputs and 7 outputs and an input vector 'R'. When using lsim thi way:

lsim(clp,R',time);

I obtain the plot correctly:

But if I want to obtain execute lsim this way:

[y,t] = lsim(clp,R',time);
plot(t,y(1,:));...

So I can save the output data inside 'y'. The problem is that when doing this the 'y' vector only contains the input response of one system, and I dont know if it is the nominal one or just the first ammog all other uncertain systems:

How can 'y' stores the rest of inputs responses so it can be plotted like on first figure.
