why not an example, that would have been so simple and clear edit

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)
