parallel.gpu.CUDAKernel Error: no entries were found in the PTX file

Hi, I am a beginner in using CUDA with matlab. From tutorial, I built a "VecSquare.cu" (code as shown below) to test parallel.gpu.CUDAKernel to launch Kernel and compute.

__global__ void VecSquare (double *A)
{    
  int i = threadIdx.x;
  A[i] = A[i] *A[i];
}

Using command " ! nvcc -ptx VecSquare.cu -ccbin "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin" ", a VecSquare.ptx file was successfully generated. But when using "k = parallel.gpu.CUDAKernel ('VecSquare.ptx', 'VecSquare.cu')", it did not pass and gave an error: Error using handleKernelArgs (line 61) No entries were found in the PTX file

I have no clues to solve this. Could you help me with this? The cuda version I used was CUDA 6.5, and VS 2010 express and 2013 professional were installed on my PC.

Thank you very much!
