scipy.spatial.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
TODO: description needed
y : (N, K) array_like
TODO: description needed
p : float, 1 <= p <= infinity
Which Minkowski p-norm to use.
threshold : positive int
If M * N * K > threshold, algorithm uses a Python loop instead of large temporary arrays.
Returns: result : (M, N) ndarray
Distance matrix.
Examples
>>> distance_matrix([[0,0],[0,1]], [[1,0],[1,1]]) array([[ 1. , 1.41421356], [ 1.41421356, 1. ]])
