The matrix equation. x ˙ ( t ) = A x ( t ) + b {\displaystyle \mathbf {\dot {x}} (t)=\mathbf {Ax} (t)+\mathbf {b} } with n ×1 parameter constant vector b is stable if and only if all eigenvalues of the constant matrix A have a negative real part. The steady state x* to which it converges if stable is found by setting.

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).
