computer setting:

Nvidia GeForce GTX 1060 + Matlab 2018a + CUDA 9.2 + WIN 10 + Visual Studio 2017 VC++ 2015.3 v140 toolset for desktop (x86,x64) has been installed and all the paths have been added. Use gpuDevice in Matlab the information can display, however the other commands cannot be executed.

e.g. Input reset(gpuDevice)

or N = 6; M = magic(N); G = gpuArray(M)

then we get

An unexpected error occurred during CUDA execution. The CUDA error was: CUDA_ERROR_ILLEGAL_ADDRESS

Does this problem related to the compatibility？ The installation is in D:/ while not the C:/ in my computer, is this related with the issue? How to solve this problem?

These issues are usually resolved by updating your NVIDIA Driver. Try getting the latest driver and see if there is still a problem. I know you may feel as though you've done this, but if you did it by downloading the CUDA 9.2 toolkit then it will not be the latest driver.
