adjacency matrix complexity的用法和样例：
- Another matrix associated with G is the adjacency matrix.
- Adjacency matrix of complex networks characterizes completely the relationship between nodes of networks, so it can perfectly describe the property of complex networks.
- A method based on adjacency matrix was presented. The fault tolerant formation could be obtained by this method.
- A(G), D(G) denotes the adjacency matrix and the diagonal matrix of vertex degrees of G, respectively.
