Graph matrix price weight length

WebDec 4, 2015 · As you can see, I mistook the purpose of the assignment and thought that just finding the difference between the two times and then storing that as the weight would work. But I need to know the difference between the departure of node x and the arrival of node y. So I think I need to pass those into the matrix and then calculate when I'm doing ... Webdistance_table calculates a histogram, by calculating the shortest path length between each pair of vertices. For directed graphs both directions are considered, so every pair of vertices appears twice in the histogram. Value. For distances a numeric matrix with length(to) columns and length(v) rows.
