Symmetry in Exponential Fourier Series¶ Since the coefficients of the Exponential Fourier Series are complex numbers, we can use symmetry to determine the form of the coefficients and thereby simplify the computation of series for wave forms that have symmetry.

The nth partial sum of the Fourier series is. You can use the following commands to calculate the nth partial sum of the Fourier series of the expression f on the interval [-L,L] syms x k L n. The next command tells MATLAB that k is an integer. https://la.mathworks.com/matlabcentral/answers/26133-fourier-series#comment_57836 Cancel Copy to Clipboard let us consider a function f(t)=20*t (0<=t<=.05) f(t) = -20*t+2 (.05 Show Hide 2 older comments.

Computing Fourier Series and Power Spectrum with MATLAB By Brian D. Storey 1. Introduction Fourier series provides an alternate way of representing data: instead of represent-ing the signal amplitude as a function of time, we represent the signal by how much information is contained at different frequencies. If you ever watched the blink-
