diameter(G)
|
|
Description
|
|
•
|
This routine uses allpairs() to compute the minimum distance between any two vertices.
|
•
|
The result is returned as a number indicating the diameter, or infinity if the graph is disconnected.
|
•
|
Edge weights are assumed to be lengths or distances. Thus edge weights must be non-negative.
|
•
|
Undirected edges are assumed to be bidirectional.
|
•
|
This routine is normally loaded via the command with(networks) but may also be referenced using the full name networks[diameter](...).
