It seems I'm late to the party - the latest release of GHC claims to
include DHP! o_O
OTOH, I can't lay my hands on any documentation, so...? (The DPH wiki
page was last updated in August
A simple and straight-forward way to define the DSP operations of
correlation and convolution is as follows:
correlate1 :: [Double] - [Double] - Double
correlate1 ks = sum . zipWith (*) ks
correlate :: [Double] - [Double] - [Double]
correlate ks [] = []
correlate ks xs = correlate1 ks xs

I think the verb is 'convolve'.
Possibly.
If ks is infinite it will not work.
Indeed.
If the correlate function could be altered to use Prelude list
functions only, I would think the above code works quite well with
stream fusion too. (Presumably you could do
