Create links between the 11 web pages A, B, ... E by typing in numbers (, indicating the number of links, usually "1"s) in the squares in the matrix to the left. Then click the "read the data" button, and press the "iterate" or "iterate 10 times" button until the results stabilize. To change the factor m, type in a different value (between 0 and 1) than 0.85, then click the "read m" button. Don't hit the "read the data" button again, since it would reset m to 0.85.
