Why is the graph not complete?
%% Problem 1_Example_17.2
display('Problem 1_Example_17.1')
ao=1/4;
an=[1/[(n^2)*(pi^2)]]*((1-(-1)^n));
N = 100000;
Wo = pi;
t = -1:.001:11;
f = zeros(1,length(t));
for n = 1:2:N
bn = (-1)^n+1;
f = f + an*cos(Wo*n*t) + bn*sin(Wo*n*t);
end
% Plotting and plot formatting is done here
plot(t,f)
axis([-1 11 -1.1 1.1])

ylabel('Function Value')
