I was looking at simulink library browser and i noticed something that i am unable to understand. I have attached a snapshot and encircled red and highlighted yellow certain items.
As you can see in attached snap, the top and first blue and yellow highlighted item simulink is also available in Library browser. why it is named like that?
And other categories encircled in red boundary for example aerospace blockset and communication blockset are not under category/heading of simulink. why? Are they not part of main simulink? are they add ons or additional components of simulink?
All of the additional Simulink library blocksets and toolboxes below the "Simulink" category require additional licenses. Use the command
license('inuse')to see which licenses you are currently using. If a license is unavailable (e.g. you're sharing them on a network, and they are all in use) then you will not be able to run any models that use those blocks.
