Witryna9 maj 2014 · I am trying to solve a 2nd order differential equation in Matlab. I was able to do this using the forward Euler method, but since this requires quite a small time step to get accurate results I have looked into some other options. More specifically the Improved Euler method (Heun's method). Witryna2 lip 2024 · The textbook I'm using states that the improved method uses the formula Yn+1 = Yn + h*(f(Xn,Yn)+f(Xn+1,^Yn+1^))/2, where ^Yn+1^ is the formula used in the …
