The issus is that you're running MATLAB on a machine that (most likely) doesn't haeve a GPU on it. You'll need to run MATLAB on an NVIDIA-enbaled GPU machine.

Sorry, I just overlooked that you're running MATLAB Online. MATLAB Online doesn't currently run on a GPU. As an alternatively, consider running MATLAB on AWS/Azure on your own, where you can select different hardware, including GPUs. Take a look at our Reference Architectures.
A couple of notes:
  1. MATLAB Online is MATLAB in a browser. The Reference Architectures are running MATLAB in a desktop environment, hosted on AWS/Azure.
  2. MATLAB Online is free to use. The Reference Architecture will incur cloud costs.

Hi Divya:
In addition to Raymond's response, if you have access to a GPU through Amazon Web Services, as well as MATLAB Parallel Server, you can access this through MATLAB Online using Cloud Center. A small video showing this capability can be found at:
