• diffhist Matrix (mathematics) 05:05 −38 Farkle Griffen talk contribs (I still take issue with the term "represent" here) Tag: Visual edit
• diffhist Matrix (mathematics) 05:03 +117 Farkle Griffen talk contribs (Re-added basic matrix operations to lead with "usually", per feedback on talk page) Tag: Visual edit
• diffhist Matrix (mathematics) 04:42 −22 慈居 talk contribs (→Abstract algebraic aspects and generalizations: place less technical material first)
• diffhist Matrix (mathematics) 04:28 +5,181 慈居 talk contribs (Technicality comes from the topic itself. The article is about matrices in general, not merely matrices over a specific field or ring. We put general cases in the generalization section to consider general readers, not because they would otherwise have undue weight.) Tags: Manual revert harv or sfn error
• diffhist Matrix (mathematics) 04:12 −5,181 David Eppstein talk contribs (I agree with SCD: this material is far out of proportion both in length and detail and in its level of technicality to the rest of the article. Matrices over semirings have applications e.g. in tropical geometry and in parallel shortest paths and context free parsing, but are too specialized for the main matrix article. See WP:DUE. At most this warrants two sentences in the "Matrices with more general entries" section.) Tags: Undo Reverted
• diffhist Matrix (mathematics) 03:55 +227 慈居 talk contribs (→With entries in a category: explain vertical and horizontal composition of 2-morphisms) Tag: Reverted

• diffhist Matrix (mathematics) 03:34 +4,965 慈居 talk contribs (recover the previous edits; the citation error is yet to resolve) Tags: Manual revert Reverted harv or sfn error
• diffhist Matrix (mathematics) 02:59 −4,965 Stepwise Continuous Dysfunction talk contribs (revert: this seems like a very lengthy addition in comparison to how much material the article has on much less esoteric topics, as well as being written at a level that presumes the reader already understands the topic; it probably belongs somewhere, but not here) Tags: Manual revert Reverted
• diffhist Matrix (mathematics) 02:52 +18 慈居 talk contribs (→With entries in a category: rephrase) Tag: Reverted
• diffhist Mathieu group 02:52 −35 66.52.150.232 talk (→In art: Assertion not supported by reference; contradicts information from earlier in the article)
• diffhist Matrix (mathematics) 02:50 +6 慈居 talk contribs (→With entries in a category: change notation) Tag: Reverted
• diffhist Matrix (mathematics) 02:47 −93 慈居 talk contribs (removed mentioning of representation (mathematics) since it is not really relevant here) Tag: Reverted

• diffhist Matrix (mathematics) 21:12 +1,008 David Eppstein talk contribs (source determinant of the empty matrix; could not source its connection to derivative of identity (one could as well say the derivative of the all-zero matrix is always zero so the 0x0 all-0 matrix should also have derivative 0))
• diffhist Algebra 03:41 −26 Remsense talk contribs (Reverted 1 edit by Rashed Aljahdali (talk): Per previous removal—it's up to you to get consensus for this addition per WP:ONUS, and you're not entitled to unilaterally impose them. the lead is written the way it is for good reasons rooted in site policy.)

• diffhist Matrix (mathematics) 17:27 −144 David Eppstein talk contribs (Undo unnecessarily technical/pedantic changes to lead (where being pedantic is the wrong place to do it) and grammatical disimprovement ("Matrices commonly related to other mathematical objects by representation" ... where is the verb?))
