Methods: linAt cosAt cubAt herAt

Hello,

I found the methods .linAt, .cosAt, .cubAt and .herAt in the following old post:

https://listarc.cal.bham.ac.uk/lists/sc-users-2011/msg01815.html

Has a Quark been released that implements these methods?
(I used these methods. After updating my OS and SC, I should add them again, and I just want to know if they are officially published).

Thanks very much!
