java.lang.Object umontreal.iro.lecuyer.hups.PointSet umontreal.iro.lecuyer.hups.ContainerPointSet umontreal.iro.lecuyer.hups.AntitheticPointSet
public class AntitheticPointSet
This container class provides antithetic points.
That is,
1 - ui, j is returned in place of coordinate ui, j.
To generate regular and antithetic variates with a point
set p, e.g., for variance reduction, one can define an
AntitheticPointSet
object pa that contains p,
and then generate the regular variates with p and the
antithetic variates with pa.
