WebSpecifies that the matrix A should be interpreted as an matrix of edge multiplicities. The entries of A must be nonnegative integers. The resulting graph is a multigraph if A has an entry greater than 1. Web17 iul. 2024 · 6.1: Graph Theory. There are several definitions that are important to understand before delving into Graph Theory. They are: A graph is a picture of dots called vertices and lines called edges. An edge that starts and ends at the same vertex is called a loop. If there are two or more edges directly connecting the same two vertices, then these ...
