I was asked to generate vector x(t), where x(t) is a rectangular pulse with width of 0.5 and period 1.
I wrote the following expression. The only thing is that I'm worried if it's a vector or not (as my English is bad).

fs = 1000; % sample freq
D = [0:1:4]'; % pulse delay times
t = 0 : 1/fs : 4000/fs; % signal evaluation time
w = 0.5; % width of each pulse
yp = pulstran(t,D,'rectpuls',w);


Thank you very much in advance!!

Still I want it as a vector, meaning I want to produce an array. I guess if...else will work...

well the thing is that I don't want to use those functions.

I want generate the rectangular function just with an

if else loop...

Thanks again!

I would like to use it. If I cannot find it, I'll use the rectpuls option....

Use Simulink "lookup table" or "pulse generator"

I finally used this way:

fs=1000; %Sample frequency
t=0:1/fs:4; %Time evaluation

y = cos(2*pi*t);

% we find positive elements and represent them as 1
y(find(y >= 0)) = 1;

% we find negative elements and represent them as 0
y(find(y < 0)) = 0;


plot(t,y),axis([0 4 -0.2 1.2])
