MATLAB plug-in for CUDA
This MATLAB plug-in for CUDA provides: acceleration of standard MATLAB 2D
FFTs and CUDA/MEX example plug-in and build environment using Chris
Bretherton's Fourier spectral simulation of 2D fluid flow MATLAB scripts from
his course material at the University of Washington.
When MATLAB makes 2D FFT calls of any size, the NVIDIA plug-in intercepts
them and handles them with a MEX file that in-turn utilizes an optimized CUDA
FFT implementation on the GPU.
This is transparent to MATLAB users. Note: this current implementation uses a
single-precision 2-FFT on the NVIDIA hardware, so the results are not in
64-bit precision that the native MATLAB implementation uses without the
NVIDIA plug-in. Can be run with and without CUDA acceleration. Time to run
the example shows a 14X speedup (from 216 seconds to 15 seconds using CUDA
via the MEX file interface).
The MEX file example and build environment uses an FS_2Dflow example but the
method is illustrative on how to write a custom CUDA interface via a MATLAB
MEX file interface for all CUDA libraries .

江城子 - 观金锁记有感
姻缘密密万家牵。寸金莲。对红鸳。花轿轻颠，行过陌阡田。瓜瓞绵延何处绝？
生注定，忆难眠。 韶光点点洒千年。只婵娟。广寒悬。薪火烟鬟，香魄
望青天。虽有黄金身上锁！双囍结，更堪怜。
