The vertex-distance-complement matrix [221-223], denoted by vcD, can be obtained simply from the vertex-distance matrix :
[vcD]ij= |
V - [vD]ii if i ≠ j |
0 otherwise (52) |
The distance-complement matrix of the vertex-labeled graph G1 (see structure A in Figure 2) is:
vcD(G1)= |

Several complement distance indices are available [221-224]: the complement Wiener index, the complement hyper-Wiener index, the complement Balaban index.
