Solve initial value problem python

WebNov 21, 2024 · Currently, I solve the following ODE system of equations using odeint. dx/dt = (-x + u)/2.0. dy/dt = (-y + x)/5.0. initial conditions: x = 0, y = 0. However, I would like to use solve_ivp which seems to be the recommended option for this type of problems, but honestly I don't know how to adapt the code... Here is the code I'm using with odeint: WebSee test_ode.py for many tests, which serves also as a set of examples for how to use dsolve().. dsolve() always returns an Equality class (except for the case when the hint is all or all_Integral).If possible, it solves the solution explicitly for the function being solved for. Otherwise, it returns an implicit solution. Arbitrary constants are symbols named C1, C2, …
