Rect function with Array

I would like to write my Rect function and I declared the following input variables:

A = 2; %amplitude

T0 = 3; %period

t = [0:Ts:T0]; %time vector base (Ts = 0.01 = time sampling)

The function I wrote is as follows:

function [y] = rect(T0, A, t)

if t < -T0/2
    y = 0;

elseif ((t >= -T0/2) & (t <= T0/2))
    y = amplitude;

else y = 0;  %if t > T0/2
    
end

I think the problem is the comparison (in the if and elseif) of the vector t with the scalar T0/2, in fact by putting a breakpoint I seem to have noticed that the comparison of the if is only performed on the first element of t (i.e. 0) .. and not with all the others.

I am asking you to suggest the right syntax to use and also (possibly) tell me if I have got the reasoning behind this function wrong.

I thought of doing a for (or while) loop inside the rect function where I increment t=t+Ts, but I would like to avoid this by using the vector t already declared incremented by Ts (as I did)

Thanks!

function [y] = rect(T0, A, t)

 y=  ((t >= -T0/2) & (t <= T0/2)) * A;

end

Thank you.

What if I want a train of pulses (rectangular) ?

How do you modify your function ?

[Matt J]

You can use the function to create several pulses and add them together.
