DC = getDiceCoeff(A,B)

Compute the Dice Coefficient, a measure of similarity between two binary (0,1) vector-sets A, B.
E.g. to compute the DC between two network community partitions, first assign each
link to the corresponding community (e.g. using 'getCommunityMatrix.m'), then binarize the cor-
responding matrix, extract the sub-diagonal elements in form of a vector. These vectors are the
required inputs, A and B.

Between others, alternative measures of similarity between sets are:

- Normalized Mutual Information ('getNMI.m')
- Jaccard Index ('getJaccard.m')


A : Binary vector of set A
B : Binary vector of set B


DC : Dice Coefficient
