描述
算子 distance_pldistance_plDistancePlDistancePlDistancePldistance_pl 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_plDistancePlDistancePlDistancePldistance_pl 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.
