Hi,

I am using a real network data from stanford SNAP webpage. Some of the nodes are labeled zeros, so I got the following error when I used graph

"Error using matlab.internal.graph.MLGraph

Source must be a dense double array of positive integer node indices."

I tried to attach the double vector but its size exceed 5 MB. Also, since this data consists of millions of nodes and links, how can I exrtact a portion of the network with couple of thousands nodes ?

This category page lists the operations you can perform on graph and/or digraph objects (a few of the operations only make sense for undirected graphs and a few only for directed graphs.)

conncomp and biconncomp in the Analyze Structure section look relevant to your question.

Thanks Steven for referring me to conncomp documentation. I was able to preprocess my large graph and all is good now.
