Implementing a step response within for loop environment?

- I'm currently working on a model that is being implemented in a for-loop environment (I know the feedback() function exists but I need to look at the signals as they loopback, and change parameters mid-loop).
- In theory, a section of the model creates a step signal that goes into a simple transfer function and continues to the rest of the model. But I'm having a hard time applying the transfer function, essentially on a per index basis.
I'm wondering if any of you have any tips or suggestions on how to proceed with this implementation. As an example, this is what the pseudo-code would look like for a sample of the model:
time = linspace(0,100,500);
for i = 1:length(time)
sig(i) = sin(2*pi*4e6*time(i) + Phase(i-1) );
% More code that uses sine wave to generate a step-like signal every now and then
% Would usually use 'lsim' to apply tf's, but doesn't work on a per-index basis in this case
StepResp(i) = tf * unitStep(i);
% More calculations
Phase(i) = .....;
end
Thank you in advance,
JH

How about trying to introduce heaviside(x) function in the sig calculation? If certain condition is met, then apply the additional step value.
