WebA differential equation is a mathematical equation for an unknown function of one or several variables that relates the values of the function itself and its derivatives of various orders. A matrix differential equation contains more than one function stacked into vector form with a matrix relating the functions to their derivatives. http://faculty.fairfield.edu/mdemers/linearalgebra/documents/2024.03.25.detalt.pdf
