 It's not "The Matrix" (film), it's

Google matrix

 From Wikipedia:

"A Google matrix is a particular stochastic matrix that is used by Google's PageRank algorithm. The matrix represents a graph with edges representing links between pages. The rank of each page can be generated iteratively from the Google matrix using the power method. However, in order for the power method to converge, the matrix must be stochastic, irreducible and aperiodic."

"The Google matrix with damping factor was described by Sergey Brin and Larry Page in 1998, see also articles PageRank and ."
