@rahulindoria5 Hi. I'd suggest starting with the CUDA Programming Guide, which you can find on the cuda website. You can also take a look at my Ph.D. thesis (you'll find it on my webpage), which contains some info on using mex-files for GPU computing in Matlab.
@quazifnatik I haven't run the code on the 580 yet (as I don't have one of those), but the code shows great scaling going from the GTX 285 to the GTX 480.
