Fourier Series Expansion Demo

GUI for visualizing the fourier expansion of 3 waves

% FourierDemo initializes an instance of the FourierDemo.fig GUI. You
% can use the scroll bar to increase the fourier series expansion of
% the selected waveform (which can be changed by the upper-right
% dropdown menu). The fourier series is represented using symbolic
% mathematics, so you must have the symbolic expansion installed with
% your MATLAB.
