ROOT 6.12/07 Reference Guide |
User class for MathMore random numbers template on the Engine type.
The API of this class followed that of the class ROOT::Math::Random It must be implemented using as Engine one of the derived classes of ROOT::Math::GSLQuasiRandomEngine, like ROOT::Math::GSLQrngSobol
