- cKDTree.query_ball_tree(self, other, r, p=2., eps=0)¶
Find all pairs of points whose distance is at most r
other : cKDTree instance
The tree containing points to search against.
r : float
The maximum distance, has to be positive.
p : float, optional
Which Minkowski norm to use. p has to meet the condition 1 <= p <= infinity.
eps : float, 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.
results : list of lists
For each element self.data[i] of this tree, results[i] is a list of the indices of its neighbors in other.data.
