Something like this
syms n t
Wo = pi;
T = 2;
n = 1:10;
a0 = (1/T)*int(t,t,0,1);
an = (2/T)*int(t*cos(n*Wo*t),0,1);
bn = (2/T)*int(t*sin(n*Wo*t),0,1);
subplot(2,1,1)
title('an');
stem(0:10, [a0 an])
subplot(2,1,2)
title('bn');
stem(1:10, bn)

Following plot actual function
syms n t
Wo = pi;
T = 2;
n = 1:10;
a0 = (1/T)*int(t,t,0,1);
an = (2/T)*int(t*cos(n*Wo*t),0,1);
bn = (2/T)*int(t*sin(n*Wo*t),0,1);
t = linspace(0, 1);
x = zeros(size(t));
x(:) = a0;
for i = 1:numel(an)
x = x + an(i)*cos(Wo*i*t) + bn(i)*sin(Wo*i*t);
end
plot(t, x)
