Can anyone please inform me why this question was deleted? math.stackexchange.com/questions/1977145/… Writing answers that disappear isn't gratifying at all. Here's the cached version: webcache.googleusercontent.com/…

@RodrigodeAzevedo The question was auto-deleted (i.e., it was not deleted by users, rather than by an automatic script).
More info on criteria for autodeletion can be found, for example, in the links collected here: meta.math.stackexchange.com/tags/auto-delete/info
If the question had at least one upvoted answer, then it would not be deleted by the script.
BTW I assume that you can see the deleted post (since you have posted answer there). There is even a link with some explanation in the banner: This question was automatically deleted. Please see the help center for more information.
@RodrigodeAzevedo If you think that the question is, for some reason, worth keeping on the site, then standard approach is to post in the designated thread. It would be good to include some argument why the question should be kept. (At least the 5 users who voted to close the question probably do not think that the question in its present form is very good.)
If you have some ideas what to add, you can even edit question to include the missing context (which was chosen as the close reason).

in Math Mods' Office, 1 hour ago, by Martin Sleziak
It would be probably better to continue the discussion there - so that we do not have discussion about the same question in two separate rooms.
Hm, it did not really work:

@RodrigodeAzevedo Roomba. It had one answer, there were no votes on the question nor the answer, and there were very little views or comments on the whole thing.

What do you think about edits which simply change mobile version of Wikipedia link to the usual one?
I found these post on the main meta: Is an edit that changes mobile links to desktop links a meaningful edit? and Automatically convert links to popular mobile pages (such as the mobile Wikipedia) to point to the corresponding regular pages.
There are not too many votes on the answers there, but it seems that general opinion is closer to: "Such edits are ok."
When I see post with mobile Wikipedia links, I am tempted to edit, by I am a bit hesitant.

@RodrigodeAzevedo BTW it is quite likely that the deleted question has a few duplicates on this site already.
This is what I was able to find:
Inverse of a diagonal matrix plus a constant
Inverse of diagonally dominant matrix with equal off-diagonal entries
Inverse of a matrix with uniform off diagonals
It seems that all of them have an answer using Sherman-Morison formula, as is the case for your answer.
duplicates One of the above questions is concerned with computational efficiency, so perhaps it can be considered different.
duplicates However, for the other two: Does the condition that the matrix is diagonally dominant actually make any difference? So perhaps they coudl be considered duplicates?

@MartinSleziak As edit suggestions, I don't like them. As edits by users with the edit privilege, unless one goes on an editing spree and floods the front page, I wholeheartedly support such edits. When one visits on a mobile device, one is redirected from the standard page to the mobile version anyway, as far as I know, and on a proper machine the mobile version is unbearable.

Hey guys. I think this question -- math.stackexchange.com/questions/1992400/… -- didn't deserve to be put on hold. Yes, the original incarnation was riddled with bad grammar (OP isn't a native English speaker) and was too biographical but I helped him trim his question down into a very specific book recommendation request. I don't think that it is more opinion-based than any other ...
book recommendation request, nor do I think it is a duplicate of the question that m_t_ links to. What do you guys think?
