scipy.spatial.cKDTree.sparse_distance_matrix¶

cKDTree.sparse_distance_matrix(self, max_distance, p)¶

Compute a sparse distance matrix

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

Parameters :

Parameters :	other : cKDTree max_distance : positive float
Returns :	result : dok_matrix Sparse matrix representing the results in “dictionary of keys” format. FIXME: Internally, built as a COO matrix, it would be more efficient to return this COO matrix.

other : cKDTree

max_distance : positive float

Returns :

result : dok_matrix

Sparse matrix representing the results in “dictionary of keys” format. FIXME: Internally, built as a COO matrix, it would be more efficient to return this COO matrix.
