public class Discrete
extends Generator
The class Discrete allows to draw integer values distributed according to an arbitrary discrete distribution. The values extracted are always in the range 0..n.

Constructor Index

o Discrete(double[])
Creates a new generator using the java standard engine and the current time as initial seed.
o Discrete(long, double[])
Creates a new generator using the java standard engine.
o Discrete(RandomEngine, double[])
Creates a new generator using the given engine.

Method Index

o draw()
Draws a value from the generator.
o setParam(double[])
Change the discrete distribution..
o type()
Returns the type of the extracted value.

Constructors

o Discrete 
 public Discrete(double c[])
Creates a new generator using the java standard engine and the current time as initial seed.

Parameters:
c - Array that contains a discrete distribution.
o Discrete 
 public Discrete(long seed,
                 double c[])
Creates a new generator using the java standard engine.
