are u planning add a FFT routines as it was in APL ?
The open source Framewave project does not currently have any DFT or FFT routines. In the proprietary version (APL), portions of the FFT library were dependant on a commercially licensed version of FFTW. Due to license restrictions, we can not open source this part of the library.
For general FFT development we recommend that you look into AMD’s ACML http://developer.amd.com/tools/acml/Pages/default.aspx. If you need an open source solution, try http://www.fftw.org/.
If you need to retain API compatibility with APL, we coudl porvide APL compatible interface on top of FFTW. We are in the process of getting this done. If there is interest, we can release it as sample code on the download site.
Let us know
