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.

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.

You need know the fuction of each wave form and use a "for" with fourier series.
For example: ![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/408130/image.png)

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);
