Fourier Series on MATLAB

How do i write code to produce periodic functions (including sinusoidal, triangle, sawtooth, square waves) and square pulse trains of varying amplitudes, frequencies, phases, and duty cycles using Fourier Series on MATLAB.

[John D'Errico]

Far too vague to get a serious answer, this question is looking for tutoring in the subject of Fourier series and in MATLAB, but is not a question about anything at this point.

Answer 1

[Setsuna Yuuki.]

You need know the fuction of each wave form and use a "for" with fourier series.

For example:

components = 1; t = 0:1e-2:10;
sumatoria = 0; i = 1;
figure;

for k = 1:1:components
    n=2*k-1;
    serie=2/pi*1/n*sin(n*pi*t);
    sumatoria = serie+sumatoria;
end

sumatoria = 1/2+sumatoria;
figure;
plot(t,sumatoria);
