Eigenvector phase portrait
Webeigenvector) tend to “hug” the straight-line solution corresponding to the weaker eigenvalue as they approach the origin. The phase portrait for this system is displayed in Figure 3.3a. In this case the equilibrium point is called a sink. More generally, if the system has eigenvalues 1 < 2 <0 with eigenvectors WebPlanar Phase Portrait. Consider a systems of linear differential equations with constant coefficients. (1) x ˙ = A x, where x ˙ = d x / d t, and A is a square matrix. When matrix A in Eq. (1) is a 2×2 matrix and x ( t) is a 2-dimensional column vector, this case is called planar, and we can take advatange of this to visualize the situation.
