Thread Subject: Displaying a matrix as a network

I have a 24x24 matrix with values ranging from -1 to 1.

What I'd like to do is have 24 nodes in a graph with connections
(lines) between each node that

a) Show whether there's a connection at all or not (by line or no
line)

and

b) Show the value of the connection (be it by line width, colour,
dashes, whatever).

Is there anything built into Matlab that can do this, or could you
point me towards some code that does?

Thanks!

I remember seeing some thing similar to this.
Here is the link.

It's the graphic analysis of the Matlab Golf contest. There are
source code there. Maybe it can give you some clues.

I've discovered biograph which is great for part a) of my question,
but not very good at showing the weights for me.
