To determine the eigenvalues, MATLAB had to solve for the roots of a polynomial of degree 13 with symbolic coefficients. This is in general only possible for polynomials up to degree 4. So you have to give values to the parameters of your function, I guess. WebOne manner that we can determine whether the integrator is stable is by plotting the eigenvalues scaled by the timestep in the complex λ∆t plane and overlaying the stability region for the desired ODE integrator. Then, ∆t can be adjusted to attempt to bring all eigenvalues into the stability region for the desired ODE integrator. Example 1. noteworthy characteristics examples https://davidsimko.com
