distance_matrix#
- scipy.spatial.distance_matrix(x, y, p=2, threshold=1000000)[source]#
- Compute the distance matrix. - Returns the matrix of all pair-wise distances. - Parameters:
- x(M, K) array_like
- Matrix of M vectors in K dimensions. 
- y(N, K) array_like
- Matrix of N vectors in K dimensions. 
- pfloat, 1 <= p <= infinity
- Which Minkowski p-norm to use. 
- thresholdpositive int
- If - M * N * K> threshold, algorithm uses a Python loop instead of large temporary arrays.
 
- Returns:
- result(M, N) ndarray
- Matrix containing the distance from every vector in x to every vector in y. 
 
 - Examples - >>> from scipy.spatial import distance_matrix >>> distance_matrix([[0,0],[0,1]], [[1,0],[1,1]]) array([[ 1. , 1.41421356], [ 1.41421356, 1. ]])
