The operator distance_pldistance_plDistancePldistance_plDistancePlDistancePl calculates the orthogonal distance
between points (RowRowRowRowRowrow,ColumnColumnColumnColumnColumncolumn) and lines,
given by two arbitrary points on the line.
The result is passed in DistanceDistanceDistanceDistanceDistancedistance.
distance_pldistance_plDistancePldistance_plDistancePlDistancePl calculates the distances between a set of n points
and one line as well as the distances between a set of n points and n
lines.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
