Arbitrary periodic signal in Simulink

Hi!

Is it possible to generate arbitrary periodic signal in Simulink? For example, I want to generate voltage signal [tex] e(t)= \sum_{n=1}^{\infty}\frac{2}{n}(-1)^{n+1}\sin{(nt)} [\tex] (Fourier series of sawtooth waveform). I wrote m-file to graph this voltage signal:

clear

clc

t=linspace(0,2*pi,1000);

suma=0;

for n=1:10000

    suma=suma+((2./n).*(-1).^(n+1)).*sin(n.*t);

end

plot(t,suma)

grid

Any idea?
