N = 1000;
vec1 = [];
vec2 = [];
tau = linspace(-1/2, 1/2, 1000);
for n = 1:2:N
    vec1 = [vec1, 1/n];
    vec2 = [vec2; sin(2 * n * pi * tau)];
end
plot(tau, vec1 * vec2)

But I don't know how to add the 4 / pi

hi Armin, here is the code to plot this square signal without sum

t = -0.5:0.001:0.5;  % Time vector
f = zeros(size(t));  % Initialize the signal
for n = 1:2:10  % Iterate over odd values of n
    f = f + (1/n) * sin(2*pi*n*t);
end
f = (4/pi) * f;  % Scale the signal
plot(t, f);
xlabel('t');
ylabel('f(t)');
title('Square Signal');
grid on;
