Are you the Jan R. Magnus listed as an author in the citations you added in your recent edit to Matrix calculus? -Apocheir (talk) 02:50, 18 February 2020 (UTC)
No, but I had to do a lot of differentiation recently and found out that his way of doing it is much better. And since his method is completely missing in the article Matrix calculus, I wanted to add it so that other people can find it easily. Matrixcalc (talk) 14:30, 18 February 2020 (UTC)
Would you be able to expand on that a little in the article? What you added says "this way is better" but it doesn't explain the new method or why it's better. -Apocheir (talk) 02:59, 19 February 2020 (UTC)
If I have some time I will add a section which explains this method. Until then "On the concept of matrix derivative" explains the differences very nicely. Matrixcalc (talk) 18:02, 19 February 2020 (UTC)
