Thread Subject: Accessing the GPU from Matlab

Does anyone have any information/resources regarding how to access an
NVIDIA GPU from Matlab to perform basic matrix operations? Maybe there
is some simple C or Fortran code that could be used to make a mex
file?

There seems to be very little out there about how to do it.

Thanks very much,

d

Search the File Exchange; there are a couple of interesting examples you
can use.

Have a look to this URL : http://www.accelereyes.com/index.php

Search for NVIDIA's CUDA technology... there's a whole load of stuff on the NVIDIA website about it. Apparently the FFTs are extremlely good.

There is a whitepaper here explaining how to do it through a MEX interface:

Hi
You can take a look at CUDA.
http://www.nvidia.com/object/cuda_get.html
Easy to create mex function for it.
Hope it can help.

Hi,

we suggest you to try the Freeware GPUmat from http://www.gp-you.org. With GPUmat you have a GPU engine from Matlab, and you easily speed up many operations.

Thanks,

is it possible to program with GPU's (NVDIA) by using jacket; its a product of accelereyes... But i not working with,( ttp://www.accelereyes.com/)... better u reffer this web page...
