I have MATLAB 2020b with a Student Licence with several toolboxes, maily on signal, antenna, and communication systems.
I haven't tested all toolboxes, but my problem began when using the Antenna Designer and Antenna Array toolboxes. I can't change parameters, see graphs, mainly anything with these apps. While monitoring with the Resource Manager of Windows 7, the memory allocation for MATLAB is normally below 2 GBs. When applying changes on parameters the memory shoots up to 6-7 GBs and stays there forever. If the parameter change doesn't freezes it, any usage of plotting tools shoots up the memory to 12-16 GBs and stays there forever, lagging and crashing my computer.
The same happens sometimes with Simulink.
Actions taken to try and fix:
  1. Stopped all non-essential processes, closed all other programs trom the Task Manager ----> no fix
  2. Re-installed MATLAB ----> no fix
My computer is a Dell Inspirion 15 5000 Series, Intel i7, 16 GB RAM, Windows 7 Pro
