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++).

BreitWignerMeanSquare
public BreitWignerMeanSquare(double mean,
double gamma,
double cut,
RandomEngine randomGenerator)
- Constructs a mean-squared BreitWigner distribution.
- Parameters:
cut
- cut==Double.NEGATIVE_INFINITY indicates "don't cut".
clone
public Object clone()
- Returns a deep copy of the receiver; the copy will produce identical sequences.
After this call has returned, the copy and the receiver have equal but separate state.
- Overrides:
clone
in class AbstractDistribution
- Returns:
- a copy of the receiver.
nextDouble
public double nextDouble(double mean,
double gamma,
double cut)
- Returns a mean-squared random number from the distribution; bypasses the internal state.
- Overrides:
nextDouble
in class BreitWigner
- Parameters:
cut
- cut==Double.NEGATIVE_INFINITY indicates "don't cut".
staticNextDouble
public static double staticNextDouble(double mean,
double gamma,
double cut)
- Returns a random number from the distribution.
- Parameters:
cut
- cut==Double.NEGATIVE_INFINITY indicates "don't cut".
