why not an example, that would have been so simple and clear
[edit]Just did one by hand to find out what was being 'exchanged' 2.103.12.172 (talk) 14:32, 25 October 2021 (UTC)

concept of "exchange matrices" seems to be non-standard?
[edit]Have been unable to find common reference to "exchange matrices" in this sense apart from the book by Johnson & Horn, which is the only source listed for the entirety of the article.
Rather, it seems to more widespread/standard idea of "exchange matrices" is akin to that of "permutation matrices", and the two are used interchangeably. 77.80.28.27 (talk) 16:53, 26 January 2024 (UTC)
