distance_matrix

scipy.spatial.distance_matrix(x, y, p=2, threshold=1000000)

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.
