Distance computations (scipy.spatial.distance) — SciPy v1.16.0 Manual (original) (raw)

Function reference#

Distance matrix computation from a collection of raw observation vectors stored in a rectangular array.

Predicates for checking the validity of distance matrices, both condensed and redundant. Also contained in this module are functions for computing the number of observations in a distance matrix.

Distance functions between two numeric vectors u and v. Computing distances over a large collection of vectors is inefficient for these functions. Use pdist for this purpose.

Distance functions between two boolean vectors (representing sets) u andv. As in the case of numerical vectors, pdist is more efficient for computing the distances between all pairs.

hamming also operates over discrete numerical vectors.
