How to create a directed graph with weights using Simulink?

How can I take a mathematically weighted digraph model and create the model using Simulink?

For those who don't know the process, I have a bunch of vertices and they are connected to other vertices via weighted arcs. Its best explained here: http://en.wikipedia.org/wiki/Directed_graph

The arrows (arc) are given a weight depending on the intensity it effects the adjacent vertex. These weights are then placed into a matrix and are used for sensitivity testing.

I was wondering how to create a model like this using Simulink so that I can run some simulations and see if I changed weights of arcs within the model how the output would be affected.

Any Simulink experts have any ideas? Thanks, Ash

Ash: I see that you have created multiple questions related to the same question (please note that it is good practice to make edits to an existing question or add comments to "bump" it up, without creating duplicates - please consider deleting the older duplicates). I'm not entirely sure that Simulink is the right domain for what you're trying to do, but I'm not an expert in other MathWorks domains (like SimEvents or SimScape). I would recommend that you look at some Simulink Videos & Examples to see if you can think of a way where you can model your problem in Simulink.

I have looked at the videos and examples, and can't seem to find anything that makes sense... but it seems so possible to do. I guess I just don't know what type of blocks to use! Any suggestions?
