Hi, I know there are similar topics to this problem, but the errormessage that I get is different to others.
My System:
Vista 32bit
Cuda 2.0
MS Visual Professional 2005
Matlab 2007b
Cuda Driver is called “NVIDIADisplayWinVista(178_08)Int.exe”
I have a 8800 GTX
This says the manual:

speed_fft
I have all these files installed and it is in the path-folder. Then I try the first command:
mex fft2_cuda.c -IC:\CUDA\include -LC:\CUDA\lib -lcudart -lcufft
Then I get this:
mex fft2_cuda.c -IC:\CUDA\include -LC:\CUDA\lib -lcudart -lcufft

??? Error using ==> mex at 206
Unable to complete successfully.
For the other both compiler-commands
mex fft2_cuda_sp_dp.c -IC:\CUDA\include -LC:\CUDA\lib -lcudart -lcufft
mex ifft2_cuda.c -IC:\CUDA\include -LC:\CUDA\lib -lcudart -lcufft
I get similar messages. When I start
speed_fft
Matlab brakes down. It closes without message.
The only idea that I still have is to install XP 32bit. But does that really help?
Hm, I really need to get that running, I hope someone can help me…
