how to format the codes to compute the differential-algebraic equations using ode15s?

Hi guys,
I’m trying to use ode15s to solve the dynamic model of a mechanical system in the form of
where M is the mass matrix, q is the vector containing all the state variables, F is the generalised force vector, λ is the Lagrange multiplier vector, and is the constraint Jacobian matrix.
To address this problem, I change the system of equations into
Then how to format the codes in Matlab? Many thanks!

I don't see a way to use a MATLAB ode integrator to solve your system.
Take a look at
Section Mechanical Systems
for suitable solvers.
