Hi all. PDL::FFTW3 is now on CPAN:
https://metacpan.org/pod/release/DKOGAN/PDL-FFTW3-0.02.1/README.pod This module is intended to be a replacement for PDL::FFT and PDL::FFTW. It is fast, has simple interfaces, and follows "normal" FFT conventions. These are similar to other numerical tools, like numpy. Specifically: - The DC component is the first entry in the transformed array - fft is unnormalized, ifft is normalized, so ifft(fft(x)) == x When using complex numbers this module expects a (real,imag) tuple in the first piddle dimension. PDL has some complex-number support in PDL::Complex, but PDL::FFTW3 does not use it, and I would strongly recommend against it. Thanks to Craig DeForest this module now has support for Alien::FFTW3, which makes installation easier on some operating systems. Let me know if any issues come up.
