WebApr 10, 2024 · 0. When I run scipy.solve_ivp with LSODA or scipy.odeint, I set an rtol and atol as well as min_step. The desired behavior is to try to reach the fixed atol/rtol, but only let the step size go so small for memory and computation purposes. If it does not reach the tolerance with h=hmin, the integration should continue, perhaps with a warning. WebNow it is time to fire up your Python interpreter. We’ll use solve_ivp in scipy.integrate - this is a high-level wrapper with lots of options for solving initial value problems. The important arguments to provide are: f(t, y) - a Python function that returns the right-hand side of the ODE - this can be a multivalued function date time in china https://casathoms.com
