Unidentified Block in Simulink

Can anyone help me out finding the block? The picture I attached is from youtube and I've trying to search on the simulink library but can't find the same block.

Hi Syahirah,

This is not some preexisiting block it is a subsystem.

For more information about the subsystem you can go through this link:

Create Subsystems - MATLAB & Simulink (mathworks.com)

Hope this helps!
