I am trying to plot this

How do i code and plot using odd harmonic of fundamental frequencies??

Try this —

t = linspace(0, 2*pi, 1E3);                         % Time Vector
x = 1:2:31;                                         % Terms Vector
f = 2;                                              % Frequency
s = sum(sin(x(:)*t*f)./x(:));                       % Signal

figure
plot(t,s)
grid
xlabel('t')
ylabel('s')
xlim([min(t) max(t)])

I will let you figure out how it works.
