Several heaviside step functions in a row

Hi there,

I am currently doing a simulation where a cell is injected with a train of currents for 2mS at every 22mS (so 2ms of current, 20ms rest) for 5 times.

This is what I have:

syms t
Iapp=(heaviside(20+2-t)-(heaviside(20-t)));

Basically, I need 4 more of this step function next to this first one. I hope my issue is understandable and someone is able to help me!

Thank you!

Iapp = sym(0);
for T = 20:20:100
  Iapp = Iapp + (heaviside(T+2-t)-(heaviside(T-t)));
end
