Web3.1.1 The Numerov algorithm After rewriting the second order differential equation to a coupled system of two first order differential equations, any ODE solver such as the Runge-Kutta method could be applied, but there exist better methods. For the special form ψ′′(x)+k(x)ψ(x) = 0, (3.4) Web26 jul. 2024 · While learning about numerical methods for solving the Schrödinger equation I came across Numerov's method. I want to get the solution for the harmonic oscillator by alreading giving the eigenvalues. The algorithm requires that I know two initial values of $\psi$ while I only know that $\psi$ must vanish at thr boundary.

Therefore, we can use the norm of the wavefunction as an indicator of the time evolution.
