Hello and thank you to whomever reads and responds to this request. I am currently trying to recreate this procedure https://faculty.csbsju.edu/frioux/scf/HESCF.pdf with never have using Mathcad. I have entered all the equations and attempted to set up a solve block but to be honest I am completely lost. I have attached my file here, if anyone could respond and show me what this in the end looks like I would greatly appreciate it.
You missed the global assignment of the variables C.j1 and C.j2 which the author had used. Thats the reason for the error when you try to define H.11.
Okay I added that,
No, you didn't! I was talking about the global assignment I see in the printout of the Mathcad sheet.
so I changed that, I am not sure on what I should do to get this to run from here
You mixed up Cj1 with Cj1 (the same with i and 2, too) quite some times! In the pdf the j (and also the i) never is in the subscript as far as I see.
Furthermore function epsilon must be defined outside of the solve block, otherwise its only known within the block.
In the definition for E.atom you had a typo (index 2 instead of 1)
See attached sheet.
