java.lang.Object umontreal.iro.lecuyer.randvar.RandomVariateGen umontreal.iro.lecuyer.randvar.RayleighGen
public class RayleighGen
This class implements random variate generators for the
Rayleigh distribution.
Its density is
f (x) | = | (x-a) e-(x-a)2/(2β2)/β2 for x >= a | |
f (x) | = | 0 for x < a, |
Constructor Summary | |
---|---|
RayleighGen(RandomStream s,
double beta)
Creates a Rayleigh random variate generator with parameters a = 0 and β = beta, using stream s. |
|
RayleighGen(RandomStream s,
double a,
double beta)
Creates a Rayleigh random variate generator with parameters a = a and β = beta, using stream s. |
|
RayleighGen(RandomStream s,
RayleighDist dist)
Creates a new generator for the Rayleigh distribution dist and stream s. |
Method Summary | |
---|---|
double |
getA()
Returns the parameter a. |
double |
getSigma()
Returns the parameter β. |
static double |
nextDouble(RandomStream s,
double a,
double beta)
Uses inversion to generate a new variate from the Rayleigh distribution with parameters a = a and β = beta, using stream s. |
void |
setParams(double a,
double beta)
Sets the parameters a = a and β = beta for this object. |
