Re: [igraph] Question on igraph_community_fastgreedy

[Richard Geddes]

Thanks.

One other question: I've learned how to play with the igraph_vector_t
container... I think Gabor showed me by example a while back... how can
I iterate through the igraph_matrix_t?   Is there a generalized
description of the igraph containers?
