We consider an unstructured planar(undirected) graph and calculate the stationary probability distribution of the randomwalk on the graph. The graph is generated by choosing n random points in the unitsquare and triangulating them using Delaunay triangulation.This sentence is from the description of a test problem in one article, I want to use this test problem, but I don't konw how to construct the matrix corresponding to this graph by Matlab.
How to construct the matrix like this
