How can i obtain response of MIMO for different 2 input?

Hi,
You can see my arbitrary state space model below. First input should be 0.1*step, and second one 100*step.
How can i define these different inputs?
Thx!

sys=ss(A,B,C,D);
step(0.1*sys)

help lsim
lsim Simulate time response of dynamic systems to arbitrary inputs.

Although lsim() as recommended by Mathieu is a general solution. However, an alternative way is to scale the B and D matrices and still use step()
sys=ss(A,0.1*B,C,0.1*D);
step(sys)
or
sys=ss(A,100*B,C,100*D);
step(sys)
