second this problem using matlabR2008B on winxp64, visual studio express 2008… not familiar enough with the code yet to know exactly what it’s taking exception to… anybody able to point me in the right direction to start troubleshooting? unsure if this is system dependent, compiler dependent, matlab dependent, or what…

Thanks,

Andy

Same Problem. I think it may have something to do with permission issues. I am not an Admin and this portion of code is attempting to write a temp directory, which may not be writable for a limited user.

I have found the solution in http://forums.nvidia.com/index.php?showtopic=67538. I use the file posted by abdelali zahi.
Now it works. But the speed seems not that fast .It shows :

nvmex -f nvmexopts.bat Szeta.cu -IC:\cuda\include -LC:\cuda\lib -lcufft -lcudart
