A Matlab toolbox to simulate light propagation for monochromatic coherent light through free-form apertures and off rough/free-form surfaces by means of a numerical approximation of the Huygens-Fresnel integral.

Toolbox features are:
* GPGPU computing, using Nvidia graphics cards with CUDA
* fallback to CPU if no GPU is found
* rough surface generation via spatial frequency filters and
surface roughness determination z=f(fx,fy,Ra)
* free form surface generation z=f(x,y)
* arrangement of objects in 3D space coordinates (6 DOF)
* rectangular 3D grids, free form apertures via logical indexing
* artificial jitter, to reduce diffraction by the input grid
* the Huygens-Fresnel approximation
* memory management, job resume if pre-existing data is found
* some examples and visualizations
