Hi, im trying to plot this fuction but im getting th 'vectors must be at the same length' error, Can anybody help to find a solution?
t=-10:10;
x = heaviside(t+2)-heaviside(t-2);
plot(t,x);
y = awgn(x,21,'measured');
plot(t,[x y]);
legend('Original Signal','Signal with AWGN');

You are concatenating x and y into a doubly long vector. If you want to plot both signals, do
plot(t,x,t,y)
