Has anyone written code to draw a digraph from an adjacency matrix? Matlab has gplot, which draws graphs given the adjacency matrix and coordinates of the nodes, but I am looking for a routine that will do something similar but also use arrows on the arcs indicating the direction of the connection. Has anyone done anything like this? I'd like to use it in my linear algebra class and do some work with digraphs.
