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.
