Write a code to compute the Fourier Series for the signal shown below.

$-$Use numerical integration to compute the Fourier coefficients from Euler's formulas.

$-$Compute the solution out to $n=1000$ for $-10t10$ with $dt=\frac{T}{500}$

$-$Save your solution in the variable $S$

Please help me write a matlab code to solve the following question, I struggle with coding!
