Hi everyone,

When computing the Bonacich centrality of a large, sparsely-connected
network (1310 vertices with 6717 edges), i get the following error message:

*Error in .local(a, b, ...) : *
*  cs_lu(A) failed: near-singular A (or out of memory)*

The graph is available via
https://www.dropbox.com/s/9ba0l3i9ozm0axe/graph.txt?dl=1 (in graphml
format).

What i have tried so far:
- using both igraphs' "power_centrality" function or the former  "bonpow"
function provide the same error
- computed eigenvector centrality (no errors), alpha centrality (same
error), computed Bonacich centrality in UCInet (no errors).
- increased memory to max (around 4GB)
- checked earlier posts and found one relevant, but unresolved thread about
six years ago:

Any help is highly appreciated, thanks in advance!

Best regards,
martin
