WitrynaCityblock Distance (Manhattan Distance) Is the distance computed using 4 degrees of movement. E.g. we can only move: up, down, right, or left, not diagonally. Example Find the cityblock distance between given points: from scipy.spatial.distance import cityblock p1 = (1, 0) p2 = (10, 2) res = cityblock (p1, p2) print(res) Result: 11 Witryna10 kwi 2024 · The code downloads Indian Pines and stores it in a numpy array.
