Re: [igraph] igraph_community_fastgreedy() in C

[Guilherme Ferraz de Arruda]

Ok, but,

I have created my graph with:

igraph_weighted_adjacency(grafo, &w_adj, IGRAPH_ADJ_MAX, 0);

can i use the name parameter as NULL at EANV()?

#define EANV(graph,n,vec)
graph: The graph.
n: The name of the attribute.
vec: Pointer to an initialized vector, the result is stored here. It
will be resized, if needed.

what is the name that i need to use?

Thanks for all.

Guilherme.
