van_der_pol_first_order#

diffeqzoo.vector_fields.van_der_pol_first_order(u, *args)#

Van-der-Pol dynamics as a first-order differential equation.

Warning

This problem has been generated by wrapping the function van_der_pol() through the function diffeqzoo.transform.second_to_first_order_vf_auto().

The problem is not originally of first order. If you have access to solvers for second-order problems, it might be more efficient to solve the original problem.
