umontreal.iro.lecuyer.randvar.TriangularGen
public class TriangularGen
This class implements random variate generators for the triangular distribution. Its density is
| f (x) = | 2(x - a)/[(b - a)(m - a)] | for a <= x <= m, | 
| f (x) = | 2(b - x)/[(b - a)(b - m)] | for m <= x <= b, | 
| f (x) = | 0 | elsewhere, | 
The (non-static) nextDouble method simply calls inverseF on the distribution.
| Constructor Summary | |
|---|---|
TriangularGen(RandomStream s,
              double m)
Creates a triangular random variate generator over the interval (0, 1), with parameter m, using stream s.  | 
|
TriangularGen(RandomStream s,
              double a,
              double b,
              double m)
Creates a triangular random variate generator over the interval (a, b), with parameter m, using stream s.  | 
|
TriangularGen(RandomStream s,
              TriangularDist dist)
Creates a new generator for the triangular distribution dist and stream s.  |
