Hi everyone,
I am experiencing an issue with MATLAB (version R2024a) on Windows 11 Pro where it fails to detect my NVIDIA T400 4GB GPU. I have already followed several troubleshooting steps without success. Here are the details of my system and the steps I’ve taken so far:
System Details:
Operating System: Windows 11 Pro Version 10.0 (Build 22631)
MATLAB Version: R2024a (Update 3)
GPU: NVIDIA T400 4GB
NVIDIA Driver Version: 516.94
CUDA Version: 11.7
Steps Taken:
Updated the NVIDIA drivers to the latest version (516.94).
Verified that the GPU is correctly recognized by the operating system using nvidia-smi:bash

+—————————————————————————–+
Ran MATLAB as an administrator to ensure it has the necessary permissions.
Checked that the CUDA environment variables are correctly set.
Set the Windows power plan to "High performance".
Ran gpuDeviceCount in MATLAB, but it does not detect any available GPU = gpuDeviceCount; disp([‘Number of GPUs available: ‘, num2str(n)]); % Output: Number of GPUs available: 0
Question:What can I do to resolve this issue and have MATLAB correctly detect my NVIDIA GPU? Are there any additional configuration steps I should follow or any other settings to check? Any suggestions or similar experiences would be greatly appreciated.
