I put in an answer for this question which the OP wants to find the saddle point equations for eigenvalues of hermitean matrices. I turned it into a minimization problem but I feel like there's got to be some linear algebra thereoms regarding Hermetian matrices that could make this easier (but I never took a college level linear algebra course)...(cont'd)
I don't know if anyone would be interested, but are there any shortcuts here to give OP a better answer?

There seems to be a Mathematica glitch where all notebooks say “ This file is currently locked by another user. You are viewing this file in read-only mode.

If you begin editing, they will not be able to make further edits”, but I am the only owner of the notebooks and no one else should be able to interact with them. Clicking “Edit Anyway” then makes “Read only” say “syncing” and then “Read only” again instantly. How is it fixed?

Nevermind. It was fixed by restarting the session
