- sys - defines your state space
- u defines your input signal which in case of step input can be defined as u=ones(length(t)) % cause we know for step u(t)=1 (you can see it from laplace transform tables)
- t - time, for example; t=linspace(0,5,10)
- x0 = is a vector of initial conditions
State Space unit step and initial conditions

I am trying to get MATLAB to show a state space response with both a unit step input and initial conditions. All documentation shows only how to do one or the other, as if I try using step() or initial(), the second overrides the first. Thanks!

The above method works but you can also use an lsim command.
Do the following:

You can get the zero input response from initial() and zero state response from step() separately, and then you can add up later to plot the response.
Then, the superposition of them is what you want. ytotal=yi+ystep; Then plot time .vs. ytotal.
