Out of memory when trying transfer learning with alexnet

I wanted to try Transfer learning with AlexNet which is available in Matlab. However, I got an error saying " Out of memory...." How can I solve this problem? I need to be able to perform transfer learning on another task and need this to work.

When I check the properties of the computer it has a CPU processor and when I right click on the desktop it seems as there is NVIDIA as well in the computer.
