Free Hyperlink Matrix

Question

I am studying Google PageRank, and require a large (1000x1000 or more) hyperlink matrix to implement in my MATLAB code. I could use random data but this is unlikely to give me good results.

Is there anywhere on the web where I can find free hyperlink matrices? Unsurprisingly, Google don't publish theirs.

Answer 1

Not entirely an answer to your question, but MATLAB's original author Cleve Moler has this book chapter all about pagerank in MATLAB.
