Inquiry on Why OCAB Isn't Incorporated into CAB Output like HAB

[nulishanganyanjiusheng1]

Author, hello. Thank you very much for your contributed code. When studying the relevant parts about OCAB and HAB, I have some doubts. I noticed that currently in the output result of CAB, HAB has been included, but OCAB has not been added. I speculate that there might be some considerations behind this. Is it because adding OCAB will cause dimension mismatch? Or is there another reason? If it's convenient, I hope you can take some time to answer my questions. This will be of great help for me to deeply understand the code logic. Thank you again!
