# How to solve 2d problems numerically.

Tags: numerically, solve
 P: 79 I havn't had much classes on numerical methods in quantum mechanics and I'm wondering how one would solve a general problem involving 2d motion. With general, I mean a problem that cannot be separated. Consider for instance the hamiltonian $\hat{H} = \frac{\widehat{p}_{x}^{2}+\widehat{p}_{y}^{2}}{2m}+x^{2}y^{2}$ How does one find the eigenvalues and eigen functions numerically?
