fftfgn

Simulates fractional Gaussian noise (FGN) *efficiently* by using the FFT.

You are now following this Submission

Generates Fractional Gaussian Noise, that is, the increments of the fractional Brownian motion.

(*) When 0<H<1/2, the Lowen's method is used to generate *exact* paths.

(**) When 1/2<H<1, a simple symmetric moving average is used.
