The parallel computing toolbox version 5.0 for MATLAB 2010b includes an initial capability for NVIDIA CUDA use. This entry provides a simple paraxial beam propagation method [BPM] solver that utilizes the added GPU capability. A script is also provided that runs the BPM with standard MATLAB Fourier transforms and the GPU implemented transforms. For smaller matrices, the standard MATLAB approach appears to be faster, while at larger matrices above 512x512 elements, the CUDA approach is more than twice as fast.An effort has been made to make the program so that it will run on a computer without the parallel computing toolbox or an NVIDIA GPU. However, a comparison with standard MATLAB is only possible with those two components.Files:The script ScrTimeBPM.mcontains an example of how one may run the main function CUDAparaxbpm.m.The additional filesFunPlotSim.mFunEfieldinit.mFunRefractIdx.minitialize the field, update the refractive index profile, and create plots.
