Try this:

f = 5;                                                                      % Frequency
N = 16;                                                                     % Order Of Harmonics
t = linspace(0, 4, 500);                                                    % Time Vector

sqwv = @(f,t,n) 4*sum(bsxfun(@rdivide, sin(2*pi*(1:2:N)'*t), (1:2:N)'))/pi;

figure
plot(t, sqwv(f,t,N))
