Subgraph centrality of a vertex measures the number of subgraphs a vertex participates in, weighting them according to their size.

The subgraph centrality of a vertex is defined as the number of closed loops originating at the vertex, where longer loops are exponentially downweighted.

Currently the calculation is performed by explicitly calculating all eigenvalues and eigenvectors of the adjacency matrix of the graph. This effectively means that the measure can only be calculated for small graphs.

A numeric vector, the subgraph centrality scores of the vertices.
