Hello!

The DifferentialEquations.jl documentation says that:

Non-constant mass matrices are not directly supported: users are advised to transform their problem through substitution to a DAE with constant mass matrices.

Am I right that there is no automated solution for write the system the way it is?

As a sample, I was guided by Matlab example " Solve Equations of Motion for Baton Thrown into Air" (sorry I can’t add link) where non-constant mass matrix M defined directly.

Is there any plans to add the possibility of using non-constant mass matrix it in the near future?

Thank you
