umontreal.iro.lecuyer.randvar.LaplaceGen
public class LaplaceGen
This class implements methods for generating random variates from the Laplace distribution. Its density is
No local copy of the parameters θ and φ is maintained in this class. The (non-static) nextDouble method simply calls inverseF on the distribution.
