Fourier

Hello,

I want to display certain functions as a fourier series (I want to perform 5 partial fourier series, or more). I want the output to be displayed as a plotted function, and also the frequency spectrum.

F.e.:

F(t)= x^3 for x=]0,3[ and (1/2)*x for x=]3,6[ with period of 2.

I've searched in the file exchange section, but didn't find anything satisfactory. Perhaps I used the wrong search items, or perhaps someone of you is having something like this?

Greetings from Germany, Manfred

Thanks "Image Analyst" and Rick, will have a look.

If you stumble-up on some complete code projects, please post them anyway. A good source is the start of a good program :)

Thank you, Manfred

Good luck.
