Graph Theory: 07 Adjacency Matrix and Incidence Matrix

The adjacency matrix of a graph and the incidence matrix of a graph are two ways to contain all of the information about the graph in a very useful format. Here we define these two types of matrices and show how to build them with an example.
Also includes BONUS FOOTAGE explaining how to define a graph by its adjacency matrix in Sage (a python-based programming language)

This video is a remake of "07 Incidence and Adjacency Matrices" with better audio and graphics.
