19 Eigenvalues, Eigenvectors, Ordinary Differential Equations, and Control This section introduces eigenvalues and eigenvectors of a matrix, and discusses the role of the eigenvalues in determining the behavior of solutions of systems of ordinary differential equations. An …

The nonzero imaginary part of two of the eigenvalues, ±ω, contributes the oscillatory component, sin(ωt), to the solution of the differential equation. With two output arguments, eig computes the eigenvectors and stores the eigenvalues in a diagonal matrix: Differential Equations and Linear Algebra, 6.5: Symmetric Matrices, Real Eigenvalues, Orthogonal Eigenvectors. In that case, we don't have real eigenvalues. In fact, we are sure to have pure, imaginary eigenvalues. I times something on the imaginary axis. But again, the eigenvectors will be orthogonal.

Eigenvalue problems can be found in every field of natural science. Clear examples are supplied by the analysis of systems of ordinary differential equations.

of linear differential equations, the solution can be written as a superposition of terms of the form eλjt where fλjg is the set of eigenvalues of the Jacobian. The eigenvalues of the Jacobian are, in general, complex numbers. Let λj = µj +iνj, where µj and νj are, respectively, the real and imaginary parts of the eigenvalue.

Consider a linear homogeneous system of \(n\) differential equations with constant coefficients, which can be written in matrix form as \[\mathbf{X’}\left( t \right) = A\mathbf{X}\left( t \right),\] where the following notation is used: Eigenvalues The number is an eigenvalue of Aif and only if I is singular: det.A I/ D 0: (3) This “characteristic equation” det.A I/ D 0 involves only , not x. When A is n by n, the equation has degree n. Then A has n eigenvalues and each leads to x: For each solve.A I/ x D 0 or Ax D x to find an eigenvector x: Example 4 A D 12 24 A has complex eigenvalues λ1 = λ and λ2 = ¯λ with corresponding complex eigenvectors W1 = W and W 2 = W .

We will mainly consider linear differential equations of the form x = Ax, but will consider a few two real solutions from the pair of complex eigenvalues a ± ib.
