Fourier Series plotting in matlab

How do you plot the first ten harmonics of a fourier series that has a dc a0 component of 1 and a bn component of (4/npi)sin(npi/2t) and no an component. This code is giving me the value of the first ten harmonics but I don't know how to plot the summation
x=3/pi;
f=0;
t=linspace(-3,2)
for i=1:1:10
an=x*1/i
f=f+an*sin(i*(pi/2).*t);
end

Is this what you are looking for? There are better ways to do it, but for now focus on learning how the figure, plot and hold commands interact.
x=3/pi;
f=0;
t=linspace(-3,2)
figure;
hold on;
for i=1:1:10
an=x*1/i
f=f+an*sin(i*(pi/2).*t);
plot(t,f)
end

If you just want the final signal:
x=3/pi;
f=0;
t=linspace(-3,2)
for i=1:1:10
an=x*1/i
f=f+an*sin(i*(pi/2).*t); % Summation Term
end
f=f+1; % Add DC A0 component to the final signal.
figure;plot(t,f);
