scipy.spatial.distance.matching

scipy.spatial.distance.matching(u, v)[source]

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.
