fseriedemo

Calculates and plots the Fourier Series Approximation to function f.

Description

FSERIESDEMO(f,b,N)
Calculates and plots the Fourier Series Approximation to function f on (0,b) with N terms. Also plots f so that a comparison can be made.

Where was this back in the Uni days...

Well done, Matt !
I have successful use it to work as datapoint [y] to fourierfit [yF] {of course ppcreate needed}

[yF,A0,re,im]=f_approxv(ppcreate(1:length(y),y,'natural'),3*length(y)/pi,fix(5.8*log10(length(y))));

The story continue to fourier_function_handle [FSyf] by {fscreate needed}
FSyf=fscreate([conj(re(end:-1:1)+i*im(end:-1:1))';A0;(re+i*im)'],2*pi);FSyf('plot');
