FOURIER

This is a program designed for first year engineering students which takes
either:
- a set of points, or
- a character string representing a function from which a set of
points can be generated

and fits a Fourier Series (with the number of cosine and sine terms
specified by the user) to the function or set of points entered. The
function (or set of points) is typed in at a terminal and a graphical
display is produced showing plots for the function and the Fourier Series.
Also available are:

- a table of errors between function and Fourier Series.

- a list of coefficients for the Fourier series.

This program can be used to fit approximations to repeating functions such
as square waves or saw-tooth waveforms.
