scipy.spatial.KDTree.query_pairs¶

KDTree.query_pairs(r, p=2.0, eps=0)[source]

Find all pairs of points within a distance.

Parameters
rpositive float

The maximum distance.

pfloat, optional

Which Minkowski norm to use. p has to meet the condition 1 <= p <= infinity.

epsfloat, optional

Approximate search. Branches of the tree are not explored if their nearest points are further than r/(1+eps), and branches are added in bulk if their furthest points are nearer than r * (1+eps). eps has to be non-negative.

Returns
resultsset

Set of pairs (i,j), with i < j, for which the corresponding positions are close.
