How do I plot the step response at t=5 using Matlab?

I have a MIMO transfer matrix, which I have decoupled, so now I have two separated SISO systems. I would like to plot the step response shifted at t=5, but I have only found how to plot the step response for t=0 in the Matlab documentation, so I have only found

step(sys)

which plots a step response starting at t=0. I would like to plot .

How can I do this? Thanks in advance.

Since:

syms s t 
stp5 = laplace(heaviside(t-5),t,s)

is:

stp5 =
exp(-5*s)/s

one approach would be to multiply it by (convolve it with) ‘stp5’, as described in: Step Response Plot of Feedback Loop with Delay.
