I will include functions from PDL::FFTW ...
PDL::FFTW only works with an outdated version of the FFTW library. If someone intelligent (that's my
escape clause) likes to rewrite PDL::FFTW so that it works with the latest version of the FFTW library, that would be a most welcome improvement to PDL. (This has been on the PDL 'todo' list for quite some time.)
Btw, ++ to you, lin0
for what you've provided in this thread.
