there are few approaches. 1) use precomputed tables from FFTW ( precomputed results are not GPL ) 2) contact MIT to purchase a license 3) rewrite using other libs ( intel Math Kernel Library ?) ( did not look in details but new delta3d also has sea surface ). Regards Sergey On Wed, May 6, 2009 at 5:11 PM, Jean-Sébastien Guay <[email protected]> wrote: > Hi Kim, Brian, > >> FFTW is GPL.
