Which method can be used to obtain the transformation matrix of the discrete Hartley transform DHT?

Multi-Dimensional Discrete Hartley Transform (MD-DHT)

Additionally, the DFT is directly obtainable from the DHT by a simple additive operation (Bracewell, 1983).

What is fast Hartley transform?

The fast Hartley transform (FHT) is similar to the Cooley-Tukey fast Fourier transform (FFT) but performs much faster because it requires only real arithmetic computations compared to the complex arithmetic computations required by the FFT.
