Is there a PDL implementation for the Discrete Cosine Transform (DCT) ?
According to Wikipedia the fftw library ( http://www.fftw.org/ ) "can compute fast DCTs (types I-IV) in one or more dimensions, of arbitrary size".
So, if you have that library, and your build of PDL includes PDL::FFTW, you might be able to do it that way - though there's no mention of discrete cosine transforms in the PDL::FFTW documentation. (Be aware that PDL::FFTW won't work with version 3 of the fftw library - the latest version it works with is 2.1.5.)
