Network Matrix:

Matrices are also used to show transport and communication links between two or more places.
Such matrices are called Network Matrices.

These matrices provide information on the number of direct links between two vertices or points (such as people or places).
A direct link is denoted by ‘1’ whereas an indirect link is denoted by ‘0’. The following example shows this more clearly:-

it seems to me that the third step in the network example is incorrect, please check the addition and the matrices that represent a and a^2
