I've encountered an issue where my GPU device isn't being recognized in MATLAB 2024a, although it was detected without any problems in MATLAB 2023b. What steps can I take to troubleshoot and resolve this issue?
here is the 2023b

I just had the exactly same issue. In 2023b, here is my GPU. I checked Device Manger and I had the latest driver from NVIDIA. Anyone can help?

Just a follow up. I found that using the Windows device manager to verify whether the latest version of GPU driver is installed is insufficient. I had to go to https://www.nvidia.com/Download/index.aspx to install the latest driver. After that, the issue was fixed. Please see below my latest GPU driver. Note that the GraphicsDriverVersion is different now.

Hi Abolfazl,
I see that MATLAB R2024a "gpuDevice" function is not detecting the GPU device. As mentioned in the Error message, did you try updating the gpu device driver to the latest version. If not, I suggest you upgrade the device drivers to the latest verion.Having the latest gpu device drivers is one of the requirements to use gpu computing capabilities in MATLAB. You can follow the below link to download latest device drivers for Nvidia GPU devices: https://www.nvidia.com/Download/index.aspx
Refer to the following documentation to know more about the MATLAB GPU computing requirements:

Hope this Helps!
