How to get Fourier series coefficients of a waveform using Matlab FFT & why is FFT plot mirrored ? @HVE

In this video I show you how to get Fourier series coefficients of a signal using MATLAB fft. I also compare the fft results with analytical calculation. Furthermore, I explain why are fft diagrams mirrored.
Fourier series and how combination of sines, cosines and a DC signal can create different waveform always amazes me when I think about it.
Q3 2021-2022 is going to end soon. Hopefully a period of less work is ahead of me.

Finance: N=42
subs=1303
Available budget (N): 1303-100-42*(42+1)=-603
Storage limit: 2^ln(1303)=144,25
