Generating a data sequence that results in this graph

Hello people,

Been racking my brain with this one. I need to write a data sequence that results in the graph below. I think I'm supposed to somehow use the unit step function and discrete delta function. I just have a really hard time figuring out how to start and what functions to manipulate.

Answer 1

Yes, unit step can be used here:

t = -10:10;
u_step = @(x) 1*(x>=0);

y = u_step(t+2) - u_step(t-5);
stem(t, y)

How can I make it so that the end points don't touch the end of the plot?

Nevermind, I realized its using the axis([]) command

[Ameer Hamza]

yes, xlim() and axis(), both will work here.

x = -5:1:10 ;
y = zeros(size(x)) ; 
y(x > -3 & x < 6) = 1 ; 
stem(x,y)

Thanks again for your clarification!
