Examples of jmt.engine.dataAnalysis.InverseMeasure

jmt.engine.dataAnalysis.InverseMeasure
It may be convenient to use an inverse measure to save computational time: Inn fact, in some cases, it's easier to analyze a measure by passing samples which are equals to 1/measure, instead of doing one division for each sample (this would make simulation much slower). At the end the correct value is passed, since the "get" methods are overridden.
