Documentation

white :: (C y, Random y) => T y Source

Deterministic white noise, uniformly distributed between -1 and 1. That is, variance is 1/3.

whiteGen :: (C y, Random y, RandomGen g) => g -> T y Source

whiteQuadraticBSplineGen :: (C y, Random y, RandomGen g) => g -> T y Source

Approximates normal distribution with variance 1 by a quadratic B-spline distribution.

randomPeeks Source

:: (C y, Random y) => T y momentary densities, p means that there is about one peak in the time range of 1/p samples -> T Bool Every occurence of True represents a peak.

randomPeeksGen :: (C y, Random y, RandomGen g) => g -> T y -> T Bool Source

randomRs :: (C y, Random y, RandomGen g) => (y, y) -> g -> T y Source
