- Does anyone have any information on the "FOUR1.C" routine in the
- Numerical Recipes in C book? I believe that the routine as printed
- (and on a source disk) does not properly compute the FFT (try a
- simple real SIN wave and examine the imaginary). Please let me know
- if I am wrong about this but it seems like the imaginary part is
- frequency reversed or something similar. Please respond via email
- if you have information or would like to hear of the results of this
- posting. Thanks.

- P.S. How can I get in touch with the company? Their Cambridge address
- is no longer valid (or at least no phone listing).
