Description🔗

The operator distance_plDistancePl calculates the orthogonal distance between points (Rowrowrow,Columncolumncolumn) and lines, given by two arbitrary points on the line. The result is passed in Distancedistancedistance.

Parameter Broadcasting🔗

This operator supports parameter broadcasting. This means that each parameter can be given as a tuple of length 1 or N. Parameters with tuple length 1 will be repeated internally such that the number of computed distances is always N.

Execution information🔗

Execution information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).

  • Multithreading scope: global (may be called from any thread).

  • Automatically parallelized on internal data level.

Parameters🔗

Column coordinate of the first point of the line.

Row2row2row_2 (input_control) point.y(-array) → (real / integer)HTuple (double / Hlong)HTuple (double / int / long)MaybeSequence[Union[float, int]]Htuple (double / Hlong)

Row coordinate of the second point of the line.
