Am I correct that any square matrix can be thought of as a directed graph? If so, how do I determine whether or not it contains cycles? Is it by looking for imaginary eigenvalues?

Yes, any square matrix can be thought of as a directed graph, particularly when you interpret the matrix as an adjacency matrix of the graph. Here's how this works and how you can determine whether the graph contains cycles:

Interpreting a Square Matrix as a Directed Graph

Adjacency Matrix: A square matrix ( A ) of size ( n \times n ) can represent a directed graph with ( n ) vertices. The entry ( A[i][j] ) indicates the presence (and possibly the weight) of a directed edge from vertex ( i ) to vertex ( j ).

Terminal Multiplexers

A terminal multiplexer mainly facilitates three things:

Create persistent terminal sessions that remain intact even when you log out of a machine--as long as the machine itself remains running. For example:

SSH into a remote machine
Start a screen session
Start a process
Log out of the machine
Log back in later, attach to the screen session, and continue working with that process.
