描述
算子 distance_prdistance_prDistancePrDistancePrDistancePrdistance_pr calculates the distance
between a point and one region.
As input the coordinates of the points
(RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn) and one
region are expected.
If a point is inside of the region, its minimum distance is zero.
The parameters
DistanceMinDistanceMinDistanceMinDistanceMindistanceMindistance_min and DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMaxdistance_max return
the result of the calculation.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
