In MATLAB please, will need codes for all parts.

MAE 376 Lab 4: Fourier Series Fourier Series Fourier Series is a representation of a function as a summation of sine and cosine functions. Any periodic Function can be expanded into Fourier series but not necessarily a finite one. To find the coefficients an and bn you can use these formulae: ao = Figure 1: Fourier Series expansion of the square wave for different values of N
