MATLAB: CUDA compatibility issues in R2017a

cudagpuarrayParallel Computing Toolbox

I have just upgraded to R2017a. Simple attempts to use gpuArray result in error messages like the following
>> gpuArray(1)
Error using gpuArray
An unexpected error occurred during CUDA execution. The CUDA error was:
CUDA driver version is insufficient for CUDA runtime version
The error message suggests that this is entirely CUDA-related, rather than MATLAB-related, but I have no such problem in R2015a and R2016b. Any ideas? My GPU information, as read in R2015a, is as follows,
>> gpuDevice
ans =

Best Answer

OK. Solved. A driver update was needed as Edric recommended. A complete computer reboot was also required.
