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.
