Solving coupled odes
WebMy MATLAB project involves analyzing the solution to 2 coupled second-order ODEs that describe the motion of a body with an implemented pendulum tuned mass damper. Currently, I have the solution to the first ODE however, the solution for my second ODE is equal to zero. I know the theory behind my code is correct but I think there is an issue ... WebNov 29, 2024 · The geodesic equation is a system of second order ODEs that can be for example solved using a runge kutta method. You can rewrite such a system into a system of first order equations and then just plug it into your solver. There's also other methods for geodesics: for example the "heat method" where you consider heat diffusion on your …
