cannam@167:The discrete Hartley transform (DHT) of a 1d real array X of size cannam@167: n computes a real array Y of the same size, where: cannam@167:
FFTW computes an unnormalized transform, in that there is no coefficient cannam@167: in front of the summation in the DHT. In other words, applying the cannam@167: transform twice (the DHT is its own inverse) will multiply the input by cannam@167: n. cannam@167:
