Web16 Feb 2024 · SciPy features two different interfaces to solve differential equations: odeint and solve_ivp. The newer one is solve_ivp and it is recommended but odeint is still widespread, probably because of its simplicity. Here I will go through the difference between both with a focus on moving to the more modern solve_ivp interface.
