63.9 AssignVertexNames

AssignVertexNames( gamma, names )

This function allows the user to give new names to the vertices of gamma, by specifying a list names of vertex names for the vertices of gamma, such that <names>[i] contains the user's name for the i-th vertex of gamma.

A copy of names is assigned to gamma.names. See also VertexName.
