jaccard_distance

jaccard_distance, a MATLAB code which computes the Jaccard distance between two sets.

The Jaccard index of two sets A and B is denoted J(A,B), and is evaluated as |A intersect B| / |A union B|.

The Jaccard distance is 1-J(A,B), which has the usual properties of a distance function.
