VariateSet

scalation.random.VariateSet
abstract class VariateSet(stream: Int)

The VariateSet abstract class serves as a base class for all the Random Variate Set (RVS) generators. They use one of the Random Number Generators (RNG's) from Random.scala to generate numbers following their particular multivariate distribution.

Value parameters

stream

the random number stream (0 until N_STREAMS)

Attributes
