I have a graph of around 3 million nodes and 10 million edges.
I want to get the cycle basis of the graph but it runs out of memory when using the command cyclebasis(G).
Is there a way to solve it?

You can't modify a file that is part of MATLAB. You could make a copy and modify that.

Hi Tala,
As per my understanding of the question, when dealing with large graphs such as the one you described, calculating the cycle basis using the cyclebasis(G) command in MATLAB may not be feasible due to memory constraints.
One way to solve this problem is to use a smaller representation of the graph. For example, you could use a sparse matrix representation, which would use less memory than a dense matrix representation
Finally, you could try to reduce the size of the graph by removing some of the edges. This could be done by using a graph simplification algorithm, such as the Kruskal algorithm or the Prim algorithm.
I hope the above information helps resolve your query.
