Beschreibung
distance_pldistance_plDistancePlDistancePlDistancePl berechnet den orthogonalen Abstand von
Punkten (RowRowRowRowrow,ColumnColumnColumnColumncolumn) zu Geraden,
gegeben durch zwei beliebige Punkte auf der Geraden.
Das Ergebnis wird im Parameter DistanceDistanceDistanceDistancedistance übergeben.
Es ist möglich die Distanzen zwischen n Punkten und einer Geraden
oder die Distanzen zwischen n Punkten und n Geraden zu berechnen.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Wird ohne Parallelisierung verarbeitet.
