错误使用 mex 命令 'nvcc' 已退出，返回值为 '2'

I use mexcuda -v filename.cu to bulid mexw64, but get error with:

命令 'nvcc' 已退出，返回值为 '2'

出错 mexcuda (line 166)

[varargout{1:nargout}] = mex(mexArguments{:});

More trouble is that, the code is correct in May, yesterday, it is wrong. I have never write it more.

could anyone help me? Thank you very much !
