- All Implemented Interfaces:
- java.io.Serializable
public class BreitWignerMeanSquare
- extends BreitWigner
Mean-square BreitWigner distribution; See the math definition.
Instance methods operate on a user supplied uniform random number generator; they are unsynchronized.
Static methods operate on a default uniform random number generator; they are synchronized.
Implementation: This is a port of RandBreitWigner used in CLHEP 1.4.0 (C++).
