i tried this but i am not sure, i think there is a mistake

t = linspace( -pi/0.01 , pi/0.01 );

for i=[1:2:5]

y=(4/pi)*(sin(i*t)/i);

end

for j=[1:2:39]

g=(4/pi)*(sin(j*t)/j);

end

plot(y ,g)

Check this code

t = linspace( -pi , pi );

y1 = zeros(size(t));
for i = 1:2:5
    y1 = y1 + (4/pi)*(sin(i*t)/i);
end

y2 = zeros(size(t));
for j= 1:2:39
    y2 = y2 + (4/pi)*(sin(j*t)/j);
end

subplot(2,1,1)
plot(t, y1)
subplot(2,1,2)
plot(t, y2)
