[igraph] Fast sum of nodes attributes

[Matheus Viana]

Hi all.

I would like to know if there is any fastest way to sum the attribute "MyAttribute" of all nodes, other than that:

double sum = 0.0;

for (node = igraph_vcount(&Graph); node--;) {

sum += VAN(&Graph,"MyAttribute",node);

}

Many thanks,
