- There is a numerical Fourier transform in the library. Its under the name FFT.
- See ?FFT for details. Also, in the Maple share library, there is a
- symbolic Fourier transform.
- You can access the Maple share library using anonymous ftp at
- daisy.uwaterloo.ca and using electronic mail by sending a message to
- maple-netlib@can.nl containing the text
-
- send info
-
- Failing that, I can send it to you.
