matching_ind
(CIJ)[source]¶ For any two nodes u and v, the matching index computes the amount of overlap in the connection patterns of u and v. Self-connections and u-v connections are ignored. The matching index is a symmetric quantity, similar to a correlation or a dot product.
Parameters: CIJ (NxN numpy.ndarray
) – adjacency matrixReturns: - Min (NxN
numpy.ndarray
) – matching index for incoming connections - Mout (NxN
numpy.ndarray
) – matching index for outgoing connections - Mall (NxN
numpy.ndarray
) – matching index for all connections
Notes
Does not use self- or cross connections for comparison. Does not use connections that are not present in BOTH u and v. All output matrices are calculated for upper triangular only.
