How to run matlab on GPU

Hi, how can I run matlab on GPU? I know the matlab should automately run on GPU but there might be something wrong with my laptop. I am sure GPU is not running at all when I run programs in matlab. What should I do?

MATLAB itself cannot run on the GPU.

If you have an appropriate GPU, and you have the Parallel Computing Toolbox, then MATLAB can run some functions on the GPU -- sending the GPU data and instructions about what is to be computed, waiting for completion, and pulling back the results. Only a subset of functions have been programmed for the GPU so far.

In order for GPU use to be a possibility, you need to be running Windows or Linux, and you need to be using a later-model NVIDIA GPU card. There is no support for Intel or AMD GPUs, only NVIDIA. No support for Apple's M1/M2 GPUs either. (It is likely to be several years before there is any support for any GPU other than NVIDIA.)

I'm not sure what you mean by "automatically". I would start with the documentation page on how to Run MATLAB Functions on a GPU, and make sure you are following those steps.

Also, make sure the Parallel Computing Toolbox is installed.
