Beschreibung
distance_ppdistance_ppDistancePpDistancePpDistancePp berechnet den Abstand zwischen Paaren von Punkten.
Der Abstand berechnet sich wie folgt:
Das Ergebnis wird im Parameter
DistanceDistanceDistanceDistancedistance übergeben.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Wird ohne Parallelisierung verarbeitet.
