Solve the 2D Gross-Pitaevskii equation for Bose-Einstein condensate in a static external potential

This function solves the Gross-Pitaevskii equation in a two-dimensional space. It may be exploited to simulate the evolution of Bose-Einstein condensate in a static external potential, or to calculate the ground-state using the imaginary time evolution.
Key features:
- Solver for the two-dimensional Gross-Pitaevskii equation.
- Arbitrary single-body initial state with closed and periodic boundary conditions.
- Bose-Einstein condensate simulations with interacting particles.
- Imaginary time evolution to calculate the ground state.
- Stationary external potential.
- Fast execution by parallelization: OpenMP.
- Multi-platform: Linux, OS X, and Windows are supported.
This function is a C/C++ subroutine and it can be called from the MATLAB® command line, as if they were built-in functions, building the MEX extension. For more information about the installation:
