scipy.spatial.KDTree.sparse_distance_matrix

KDTree.sparse_distance_matrix(other, max_distance, p=2.0)

Compute a sparse distance matrix

Computes a distance matrix between two KDTrees, leaving as zero any distance greater than max_distance.

Parameters:

other : KDTree

max_distance : positive float

p : float, optional

Returns:

result : dok_matrix

Sparse matrix representing the results in “dictionary of keys” format.
