      extended by umontreal.iro.lecuyer.randvar.UniformGen

public class UniformGen
extends RandomVariateGen

This class implements random variate generators for the (continuous) uniform distribution over the interval (a, b), where a and b are real numbers with a < b. The density is

f (x) = 1/(b - a)         for a <= x <= b.

The (non-static) nextDouble method simply calls inverseF on the distribution.


Constructor Summary
UniformGen(RandomStream s, UniformDist dist)
          Creates a new generator for the uniform distribution dist and stream s.
 
Method Summary
 double nextDouble()
          Generates a random number from the continuous distribution contained in this object.
static double nextDouble(RandomStream s, double a, double b)
          Generates a new uniform random variate over the interval (a, b) by inversion, using stream s.

Constructor Detail

UniformGen

public UniformGen(RandomStream s,
                  UniformDist dist)
Creates a new generator for the uniform distribution dist and stream s.

Method Detail

nextDouble

public double nextDouble()
Description copied from class: RandomVariateGen
Generates a random number from the continuous distribution contained in this object. By default, this method uses inversion by calling the inverseF method of the distribution object. Alternative generating methods are provided in subclasses.

Overrides:
nextDouble in class RandomVariateGen
Returns:
the generated value

nextDouble

public static double nextDouble(RandomStream s,
                                double a,
                                double b)
Generates a new uniform random variate over the interval (a, b) by inversion, using stream s.
