I want a matrix (like the degree correlation matrix) with the probabilities of finding a node with y-value i and j at the two ends of a randomly selected link. I guessed that this is somehow similar to a degree correlation matrix but instead of the node degrees I use the y-values of gg.
I called it 'degree correlation matrix' because the node values do not rely on the degrees of the node.
