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
