Finally, the ODE function must reshape its output back into a vector so that the ODE solver receives a vector back from each function call. If you follow these steps, then the ODE solver can solve the system of equations using a vector for the solution components, while the ODE function ...

Yes, I solve my system of 200 ODES with ODE15S in matlab, and it takes much more time to execute than RKF45 solver in dummy C program. So it grieves me so much =) Stiff solver gives no visible advantage in efficiency. As I remember Runge-Kutta methods may be parallelized. I wounder...

How to solve this system of ODEs? I was try to study a dynamical system and for that after accounting for all factor I got the following system of differential equations: [1] and, [2] where c is a constant. I want to find a solution to these differential equations. Is it possible ...

However, no scheme of acoustic computing device with more complex functionality has been proposed, such as ordinary differential equation (ODE) solver. Here, we propose an acoustic analog computing (AAC) system based on three cascaded metasurfaces to solve thenth-order ODEs. The metasurfaces are ...
However, as it changes the velocity directly, the traditional ordinary-differential-equation (ODE) solver cannot be used. Therefore, for the multibody system that consists of bodies that are connected by joints, the impulse-based method is not applicable. Jeong et al. (2016) applied this method...
