MATLAB R2014a in Ubuntu 14.04 doesn't recognize NVIDIA GeForce GTX770

Hi,
I'm running MATLAB R2014a (with parallel computing toolbox) on Ubuntu 14.04, and I have a GeForce GTX770 GPU with computing capability 3.0, but MATLAB seems not to recognize it. The output of a couple of commands is
>> gpuDevice
Error using gpuDevice (line 26)
No supported GPU device was found on this computer. To learn more about supported GPU devices, see
www.mathworks.com/gpudevice.
>> parallel.internal.gpu.CUDADriverVersion
Error using parallel.internal.gpu.CUDADriverVersion>iLinuxDriverVersion (line 105)
Could not read version information from '/proc/driver/nvidia/version'.
Error in parallel.internal.gpu.CUDADriverVersion (line 15)
However, in the terminal I get
~$ lspci -vnn | grep VGA -A 12

Kernel driver in use: nouveau
so the card is there. How can I make MATLAB recognize the card? Is it related to be using the 'Nouveau' driver instead of Nvidia's?
Thanks,

Yes, it is because you are using the "nouveau" driver. You need to get a compute driver from the NVIDIA website.

This worked for me. I'm running ubuntu 16.04 (Xenial Xerus) on Lenovo-IdeaPad-Y510P. I simply went to Additional Drivers and switched to Nvidia proprietary drivier over the neouveau drivier, hit "apply changes", then restarted my computer. MATLAB automatically recognized the change. I confirmed this with "opengl info" in MATLAB, which showed that opengl was using hardware rendering with the Nvidia graphics card.

Hello, I have nVidia Quadro 6000, and the same problem. I have no "nouveau" driver.
