My matlab just crashed when I was using CUDA kernel, before it ran like a charm. After restarting the computer, it still does not run properly. Matlab can still run on CPU parallel and define GPUArrays, but whenever I call GPU CUDA Kernel, it pops a window saying matlab encounters an internal problem and has to close. I sent out the automatic report once. I think my NVIDIA cards are fine, since I can still run their cuda samples on command prompt. Would you please help me with this? Thank you so much!

Were you able to execute this kernel code successfully outside of MATLAB?

Do you call the CUDA kernel with indexed variables as input? I had the same problem when using a kernel with indexed input such as input(1,[1 2 3]) where input was data on GPU. In this case it helped to define the index outside the function call and use the kernel with input(1,index) where index=[1 2 3] was defined before using the kernel.
