Matrix differential equation

A matrix differential equation is like a regular equation, but it uses matrices - special kinds of tables with numbers in them - instead of regular numbers. A matrix equation can have numbers on one side and a matrix on the other side. To figure out the answer, you have to use an equation to change the matrix back into numbers. This is a little bit harder than a regular equation, but it still follows the same overall rules.
