- I've been using the Fourier[] command to find the discrete
- Fourier transform of a list. When I
- ListPlot[Abs[Fourrier[...]]] as in the book I sometimes get
- strange points scattered arround, even negative ones.
- This happens with 256 sample points (as in the example in the book)
- but 64 does not give this problem. I am using 2.0 for DOS
- Does anyone have experience with this problem? please post
- or mail to MEYEROWI@acc.fau.edu. Thanks!
