Hi Sania,
  • If you're training your network, you need to set 'ExecutionEnvironment' to 'gpu' or 'multi-gpu' in trainingOptions. The doc for trainingOptions is here.
  • If you have already trained your network and you want to use it, you can either set the option 'Acceleration' to 'MEX' in the function predict or you can use GPU coder as shown in this other doc page.
Note that (as of today) you can't use GPU coder to train your network.

So the first step is to check whether you have the "Parallel Computing Toolbox" with:
if the toolbox isn't in the list, than you need to buy it.
Then, take a look at the documentation from mathwork about computing on GPU.
Hope it help you.
