Hi all,
I have the following code lines execuding an error message:
>> size(img)
ans =
215 205 156 8
>> img_gpu = gpuArray(img);
Unable to load CUDA driver. The library name used was nvcuda.dll. The error was:
nvcuda.dll is not a valid Win32 application.
Update or reinstall your GPU driver. For more information on GPU support, see GPU Support by Release.
I have updated my GPU driver and installed the CUDA Toolkit 11.2 on my Windows 10 with a Intel(R) UHD Graphics 620. I have Matlab 2020a for 64-bit.
I found the similiar problem documented here.
Can somone recommend me a solution?

Make sure you've rebooted the computer after the installation.

Yes, I have tried that several times. I have a feeling that my GPU is maybe not suitable for this application.

Matlab R2020a requires CUDA Toolkit 10.1.

I'm not sure the CUDA Toolkit version from that table is required unless you are using it to compile CUDA mex files that Matlab will invoke.

I have tried that, rebooted and it still doesn't work. I also want to point out again, that I have a GPU by Intel
