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. How are those initial values found? Also it would be great if someone could refer me to some resources for this method.
