Returns the vectors of indirect dependences according with the PageRank method and plot the values in a bar graphic.
d = pagerank(D,p,keyword) // Show the vector of of indirect dependences d and the bar plot of the result using the keyword algorithm.
A word that define the method to use. Valid words are: limit, matlab, power and sparsepower. This is mandatory.
Value of the parameter for the PageRank method, look the bibliography.
Transpose of the adjacency matrix of a graph.
Name of the variable to store the indirect dependences vector.
This function gives the vector of indirect dependences and the matrix of indirect influences of a given matrix of direct influences according with the PageRank method. You only need to declare the adjacency matrix of the graph, the function makes all the process. This method does'nt support polynomial matrices.
D = [1 0 1;0 0 0;0 0 6] // Define the transpose of the adjacency matrix of a graph. d = pagerank(D,0.85,'limit') d = pagerank(D,0.85,'matlab') d = pagerank(D,0.85,'power') d = pagerank(D,0.85,'sparsepower') d = pagerank(D,0.85,'inverse') D = sparse([1,2;2,3;3,1],[1,2,4]) // Define a sparse matrix d = pagerank(D,0.85,'limit') d = pagerank(D,0.85,'matlab') d = pagerank(D,0.85,'power') d = pagerank(D,0.85,'sparsepower') | ![]() | ![]() |
