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 ... WebJul 24, 2015 · For example, if a = 1 we get the second equations as. (1) [ 1 2] H ′ + [ 1 − 2] H = 0. which is, in fact, dependent (minus the derivative of ( 1)). Solving the equation ( 1) gives you the dependence between F and G (the whole subspace of solutions) ⇒ F ( t) + 2 G ( t) = 4 ∫ e s − t G ( s) d s. Similar for a = − 1.
