Expand description

SIMD-accelerated batch distance computation for KD-Tree queries

Computes squared distances from a query point to multiple data points. Used for efficient k-NN search in KD-Trees.

§Arguments

  • query_point - Query point
  • data_points - Matrix of data points (n_points x n_dims)

§Returns

  • Array of squared distances

§Errors

Returns error if dimensions don’t match
