| Nov 18, 2020 at 16:02 | comment | added | Teo Protoulis | When $K$ is small the solver won’t converge and either gets stuck at some time instant or results are completely wrong. The fact is that I want to simulate a 7-DOF manipulator after that so computing the jacobian would be my very last choice. I am just passing the sparse matrix as ode option to the solver. Do you mean that although I am solving this system and not the $M(q)\ddot{q}$ I should put the mass matrix as ode option ? | |

What happens when $K$ is small? ode15s doesn't converge? Is there anything preventing you from computing the Jacobian? Unless your mass matrix is very simple, I would recommend using the Mass option for odeset so the inverse of the mass matrix doesn't make the Jacobian any more complex.
