Draw Network in Matlab

I need to draw a netw开发者_如何学编程ork (not a neural network) with 5 nodes and 20 directed edges (an edge connecting each 2 nodes), and I need to be able to control the thickness of each edge. Is there a toolbox in Matlab offering this?

Thanks in advance.

Yes, Bioinformatics Toolbox will allow you to do this with the biograph command.
