Schrodinger Equation Finite Difference Matlab
grid and replacing derivatives with difference equations. For the second derivative in the Schrödinger equation, the central difference approximation is: \[ \frac{d^2 \psi}{dx^2} \approx \frac{\psi_{i+1} - 2\psi_i + \psi_{i-1}}{\Delta x^2} \] where \(\Delta x\) is t
