While some of the statements could be cited to the mathematical data included in the article, other prose (such as in the "History" and "Electronics" sections) needs to be cited. Z1720 (talk) 05:56, 3 May 2025 (UTC)

:There were not before the GAR was opened and still are not any cleanup tags on this article such as [citation needed]. The only actual error category on the article is the newly-instantiated ISBN-date mismatch. Therefore, to me, starting the cleanup process by immediately opening a GAR seems like an excessively strong first measure. Maybe it would have been less confrontational to have tried placing [citation needed] tags first, and then waited enough time to see whether they were addressed, disputed, or ignored before opening a GAR? Even now that the GAR has been opened, you could still place those tags. Doing so would make it more clear to editors what you think is inadequately cited rather than this vague wave which leaves much to the imagination and makes it impossible to determine whether any steps one might take would satisfy you.

:To put it another way: the preferred outcome of a GAR is to restore an article to deserving GA status, not to delist. If cleanup tags can head off a GAR before it starts, that would be even better. And telling us that the article is inadequate without providing specific-enough guidance for why you think so is a step towards the non-preferred outcome. —David Eppstein (talk) 07:38, 3 May 2025 (UTC)

::@Z1720 can you provide some citation needed tags and other tags for describing the problem you have listed? As for a quick note, I am pinging @Jakob.scholbach as the nominator in 2009. Dedhert.Jr (talk) 07:52, 3 May 2025 (UTC)

::*{{re|David Eppstein}} Some editors have described the addition of citation needed templates as disruptive, which is why I only add them when asked. I have now added some where I think they are needed and I see that other editors have also added cn templates to the article. If any editors are concerned about my conduct in GARs, please open a new thread at WT:GAN where the conversation may be more appropriate. Z1720 (talk) 15:47, 3 May 2025 (UTC)

::*:I did open a thread about WT:GAN, not about you specifically but about whether it is reasonable to expect that an article not tagged for any problems to suddenly come under GAR. And in that thread, you deflected again, saying that you would rather be pinged than discuss things there. —David Eppstein (talk) 17:59, 3 May 2025 (UTC)

:::Unfortunately, Jakob.scholbach appears not to have been active for almost a year. Fortunately, matrices are a basic enough topic that any other mathematician should be able to contribute, without requiring any special expertise. —David Eppstein (talk) 18:01, 3 May 2025 (UTC)
