Texture array

Sorry for post this again.

I want to deal with many images in one kernel, and want to load the images as texture, so I think it is ok to use texture array.

I also tried to modify the simpleTexture sample as following

texture<float, 2, cudaReadModeElementType> tex[1]

and change the corresponding codes.

The compiler reported that

#error: identifier “tex” is undefined#

in the kernel code

Maybe my usage is not right.
The programming guide did not mention how to use texure array.

Any idea, please.
