By writing some program code I got an output y = exp(-2*t)/2 - exp(-t) + 1/2. I want to separate out 1/2 from it. What command shall I use to get the steady state value (t = infinity) of the function (which is 1/2 in this case). I can also put t = 10000(some large value) to get my steady state value if infinity is not possible.So it boils down to finding the value of the function at a particular time. How should I do it?

If somebody search on google how to find steady state value or final value of an LTI system step response (transfer function, state-space, etc) then you can find it using dcgain function
