• 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) 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) 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))
