[igraph] : Adjacency Matrix

[patricia]

Hi,

To use igraph_adjacency function () I need to create a variable of type igraph_adjacency_t or simply use the following syntax: igraph_adjacency (& net, & adj, IGRAPH_ADJ_UNDIRECTED)?

You can use the SETEAN () function before creating the graph, or only after its creation is possible to set the numerical values of the edges?

Thank you
