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 :

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.

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.
