Class UniformRandomGenerator

java.lang.Object

org.apache.commons.math3.random.UniformRandomGenerator

All Implemented Interfaces:

NormalizedRandomGenerator

public class UniformRandomGenerator
extends java.lang.Object
implements NormalizedRandomGenerator

This class implements a normalized uniform random generator.

Since it is a normalized random generator, it generates values from a uniform distribution with mean equal to 0 and standard deviation equal to 1. Generated values fall in the range [-√3, +√3].

Since:

1.2
