How can i plot a unit step function or a piecewise function in Matlab?
ie:
h(t)=u(t-2)-u(t-4)?
or another example:
h(t)={0 for t<0, 1 for 2<t<3, 0 for t>3
Also, how can i plot a periodic square wave with thresholds in matlab?

This sounds like homework. If so, show what you have tried so far, and ask some specific questions where you are stuck. If you have literally no idea where to even begin, I suggest you go back to your teacher and seek help.

t=0:0.001:4;
h=(t-2)-(t-4);
subplot(2,1,1)
plot(t,h)
Sorry, yes I am very new to it and just starting out. Dont want to bother you, just seeking advice that can make me underdatand, and yes i have very little idea to even where to begin and if you have any good books or any resources for beginners in signal processing and general MatLab functioning, or even on some fundamental coding techniques needed to suggest, it would be greatly appreciated.
heaviside was what I was looking for!
Many thanks for your support.

This is my proposal, I hope it helps you:
u = @(t) double(t>=0);
h = @(t) u(t-2)-u(t-4);
fplot(h,[0,5])
