Computing average path length

I'm using karate.gml dataset, from two visualization software gephi and SocNetV both gives me an average path length of 2.408. I want to compute the average path length in matlab using the same dataset, but mine gives me 1.76. My matlab procedure is below:
I add the distance {d} returned by the shortestpath function {[P,d] = shortestpath(G,c,nodesize);} to an array I've declared and afterwards find the mean. Not sure what I'm doing wrong.
size = nodesize;
x = [];
for c = 1:size
[P,d] = shortestpath(G,c,nodesize);
x = [x, d];
end
answer = mean(x)

I would tend to think that average path length would include alternative paths, not just the shortest path.
