This code solves the time independent Schroedinger equation in 2D with a constant mass.
It uses 2 different algorithms that can be switched ON/OFF:
-> The FDM: Finite Difference Method
-> The PWE: Plane Wave Expansion method that solves the equation in the Fourier space
Three different potentials are proposed:
-> The Rectangular potential
-> The Elliptical potential
-> The Hexagonal potential
Any potential can be loaded with homogeneous grid x,y [m] and V [eV]
