An nxn system of ODEs looks like the following

In vector form, the same equation can be written as

Non-linear ODEs are very complicated (like chaos theory, three body problem, etc.). This page will focus entirely on linear systems, which can be expressed as

where P is the nxn coefficient matrix.
