cannam@127:The discrete Hartley transform (DHT) of a 1d real array X of size cannam@127: n computes a real array Y of the same size, where: cannam@127:
FFTW computes an unnormalized transform, in that there is no coefficient cannam@127: in front of the summation in the DHT. In other words, applying the cannam@127: transform twice (the DHT is its own inverse) will multiply the input by cannam@127: n. cannam@127:
