Unreleased

Changed

  • BallTree and VantagePointTree accept an ndarray as a point.

0.4.0 - 2020-06-01

Added

  • A vantage point tree data structure to find nearest points.
  • BallTree accepts not only an f64 array but also an f32one.
  • BallTree::euclidean to create a ball tree withoug having to pass a distance metric as an argument.

Changed

  • The codinates of each point must be stored in a contiguous area in memory.
  • A distance metric is now a function, not a trait.

0.3.0 - 2020-04-17

Changed

  • The ownership of the input can be transferred to BallTree, which accepts both an owned array and a view.
  • An error is returned, rather than a panic, if an empty array is given to construct a BallTree.
  • query_one has been renamed query_nearest.
  • query returns indices and distances separately, so that data of the same type are stored together.

0.2.0 - 2020-04-09

Changed

  • BallTree takes ArrayBase as its input, instead of ArrayView, to allow more types in ndarray.

0.1.0 - 2019-11-20

Added

  • A ball tree data structure to find nearest neighbors.
