Problem:
Consider a periodic, with period unity, signal with a cycle that is square cornered pulse of width w with an amplitude of a and a middle of m. Use numeric Matlab to plot several cycles of the periodic signal for various values of the cycle parameters.
Here's my code:
My problem here is, how would I make this single box into a periodic one with several cycles? I already tried adding several boxa's, but it did not work. I also tried using the Matlab function, square(x), but I'm not sure if that function would help me choose an amplitude and width of the box.
Can someone please help me?

Rich (BB code):
%--------------
dt=.01;t=-5:dt:5;f=-1/2:dt:1/2; % Time & Freq Vectors
a=2;w=4; % Parameters: a=amplitude, w=width
boxa = ...
(a*1) .* (abs(t)<w/2) + ...
(0) .* (2>=abs(t)>w/2);
eboxa=dt*boxa*boxa';boxa=boxa/sqrt(eboxa); % Energy of box
pboxa=(abs(boxa).^2)/eboxa; % Density of box
mboxa=dt*sum(t.*pboxa); % Middle of box
plot(t,box)
