DistanceFunction
DistanceFunction
是诸如 Nearest 之类函数的一个选项，指明假定任何两个确定点之间的距离值.
更多信息
- DistanceFunction->f 指明 x 和 y 之间的假定的距离应当是 f[x,y].
范例
基本范例 (2)
用 ChessboardDistance 求出最靠近 {5,5} 的点：
Nearest[{{5, 9}, {2, 4}, {3, 8}, {0, 8}, {5, 2}}, {5, 5}, DistanceFunction -> ChessboardDistance]Nearest[{{5, 9}, {2, 4}, {3, 8}, {0, 8}, {5, 2}}, {5, 5}]用 DiceDissimilarity 求出布尔数据集：
data = {{1, 0}, {0, 1}, {0, 0}, {1, 1}, {1, 1}, {1, 0}, {0, 1}, {0, 1}};FindClusters[data, DistanceFunction -> DiceDissimilarity]FindClusters[data]
