scipy.spatial.distance.matching

scipy.spatial.distance.matching(u, v)

Computes the Matching dissimilarity between two boolean 1-D arrays.

The Matching dissimilarity between two boolean 1-D arrays u and v, is defined as

\[\frac{c_{TF} + c_{FT}}{n}\]

where \(c_{ij}\) is the number of occurrences of \(\mathtt{u[k]} = i\) and \(\mathtt{v[k]} = j\) for \(k < n\).

Parameters:

u : (N,) array_like, bool

Input array.

v : (N,) array_like, bool

Input array.

Returns:

matching : double

The Matching dissimilarity between vectors u and v.
