WitrynaThe improved Euler method has better accuracy than the forward or backward Euler methods, and it is also unconditionally stable. Since the right-hand-side is to be taken at the uknown value yk+1, the method is implicit, i.e. a root finding algorithm has to be used to find the value of yk+1 in the iterative scheme.

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.
