MATLAB does not recognize my GPUs for cuda execution?

I open Matlab and run gpuDevice(), it gives at UBUNTU 13.10 ;

    Error using gpuDevice (line 26)
    An unexpected error occurred during CUDA execution. The CUDA error was:
    CUDA_ERROR_UNKNOWN
    and

if I run gpuDeviceCount(), it returns 0

However if I run nvidia-smi from terminal it shows all the available GPUs and their stats.

I installed both cuda 5.5 and cuda 6.0 but same for both.

Any idea what is the reason behind for such a malfunction?
