Coupled matrix and matrix differential equations have also been widely used in stability theory ... Liv-Ari [13] described an alternative approach based on:.

The system of differential equations can now be written as d⃗x dt = A⃗x. The trick to solving this equation is to perform a change of variable that transforms this differential equation into one involving only a diagonal matrix. Using the eigenvector procedure, we can find a matrix( P so that P−1AP = λ1 0 0 λ2).
