Details:

> c = @(f, T, n, t) (1/T)*trapz(t, f(t).*exp(-j.*2.*pi./T.*n.*t))
> four = @(f, T, n, t) sum(arrayfun(@(N) c(f, T, N, linspace(0, T,
100)).*exp(j*2*pi/T*N*t), [-n:n]))
> afour = @(f, T, N, t) arrayfun(@(x) four(f, T, N, x), t)
> save fourier

The printed representation of four/afour is incorrect, for instance:

afour =

@(f, T, N, t) arrayfun (@(x) four (f, T, N, x);
, t)

This of course prohibits loading the file; the file will only load after
manual correction to the entries for four/afour.

octave:1> load fourier
parse error:

  syntax error

>>> @(f, T, N, t) arrayfun (@(x) four (f, T, N, x);

Attached is the file "fourier" produced by the command "save fourier".
