Matlab throws and error while using gpuDevice. It asks for CUDA driver newer than 10.1. I have 10.2 installed.

If I run the command gpuDevice, I get the following error,"Error using gpuDevice (line 26)
CUDA driver version 9 is not supported. Update CUDA driver to version 10.1 or greater. For more information on GPU support,
see GPU Support by Release."
I am positive that I have installed CUDA driver 10.2.

If you run nvidia-smi it will tell you the driver version you are running. On Linux it should be on the path, on Windows it's in "C:\Program Files\Nvidia corporation\nvsmi\nvidia-smi.exe"
Output will look something like the following:
