Witryna12 kwi 2015 · Euler method is horrible for general ODE timestepping because it is globally only first order accurate. This means that to decrease the error by a factor of 1/2, you'll need to decrease the timestep by half. Effectively, this also means that you'll need twice as many timesteps to improve your accuracy at the same final timestep.
