pyann 0.0.1

Python wrapper for Arya and Mount's ANN library (v1.1.3)

PyANN

Finds the k nearest neighbours for every point in a given dataset in O(N log N) time using Arya and Mount's ANN library (v1.1.3). There is support for approximate as well as exact searches, fixed radius searches and bd as well as kd trees.

This package implements nearest neighbors for the Euclidean (L2) metric.

For further details on the underlying ANN library, see http://www.cs.umd.edu/~mount/ANN.

PyANN was written to be the Python equivalent of the R package RANN. For further details on the R implementation, see RANN.
