Graphs, Networks, and Incidence Matrices  Lecture 12. An indepth discussion of small realworld graphs and their nodes / edges.
 What is the node of a graph?
 What is the edge of a graph?
 What is an example of a realworld directed graph?
 What is an incidence matrix?
This is a very realworld oriented video with small directed graphs and incidence matrices describing the nodes and edges of these graphs. This video gives meaning and purpose to matrices.
