Compute (matlab sheet 1) the page rank for a simple graph of 7 nodes as described in the class notes. For a large random graph compare computations in matlab sheet 2. Both sheets also show the influence of additional 'bought' links. For background on pagerank see for instance the Wikipedia entry. An example of how page rank can be gamed in a NYT article, breakdown in class slides Matlab sheets that illustrate the approximation of a function by Legendre and Chebyshev orthogonal polynomials,
