Numerical Evaluation of Fourier Series Code

The code to find the Fourier Coefficients numerically is given. The specific function evaluated comes from the complicated example page. Using Matlab, the code is given in Figure 1. Figure 1. The Matlab Code for the Fourier Series Coefficients. Note that the discrete integrals are simply found from summing up the value of the function, weighted by delT, which is similar to dT in the continuous form of the integral.
