NLSEmagic is a package of C and MATLAB script codes which simulate the nonlinear Schrödinger equation in one, two, and three dimensions.  The code includes MEX integrators in C, as well as NVIDIA CUDA-enabled GPU-accelerated MEX files in C.  The MATLAB script files call the compiled MEX codes forming an easy-to-use highly efficient program.  The codes utilize a fourth-order (in time) Runge-Kutta scheme combined with the choice of standard second-order (in space) finite differencing, or a compact  two-step fourth-order (in space) finite differencing.

The code was developed as part of my Ph.D. dissertation, and includes two versions.  One is a streamlined easy-to-follow script code which is meant as an example of how to use the MEX codes, while the other version is a full-research code which can reproduce my research results.

NLSEmagic is freely distributed for use and modification.  However, a nominal donation and acknowledgment of authorship is appreciated.

NLSEmagic is in the process of being updated to version 020. The 1D code is now available! Further updates to come. (07/16/14)
