Count routes using powers of a connection matrix
The network shows computers that can send data through relays. Each line is one two-way data link
Use the order Desktop, Printer, Laptop for the rows and columns of connection matrix \(C\). Rows name the starting vertex and columns name the ending vertex
\[C = \begin{bmatrix} 0 & 0 & 2 \\ 0 & 0 & 1 \\ 2 & 1 & 0 \end{bmatrix}\]
