public class NakagamiGen
extends RandomVariateGen

This class implements random variate generators for the Nakagami distribution. See the definition in NakagamiDist of package probdist.

Constructor Summary

NakagamiGen(RandomStream s, double a, double lambda, double c)
Creates a new Nakagami generator with parameters a = a, λ = lambda and c = c, using stream s.

NakagamiGen(RandomStream s, NakagamiDist dist)
Creates a new generator for the distribution dist, using stream s.

Method Summary

double	getA() Returns the location parameter a of this object.
double	getC() Returns the shape parameter c of this object.
double	getLambda() Returns the scale parameter λ of this object.
static double	nextDouble(RandomStream s, double a, double lambda, double c) Generates a variate from the Nakagami distribution with parameters a = a, λ = lambda and c = c, using stream s.
