Talk:Conjugate transpose

One more way of denoting the conjugate transpose?

Why aren't "*T" listed as a possible notation for the conjugate transpose? This notation, which I've previously encountered in statistical signal processing, is presumably more intuitive, since it really is just a combination of conjugate and transpose. --Fredrik Orderud 00:57, 21 Apr 2005 (UTC)

I never encountered the notation as you say, $A^{*T}\,$. I'd say it looks a bit clumsy. Besides, note that in this article (and in many other places) they use the bar for the conjugate, so then your notation might need to be changed to ${\overline {A}}^{T}$.

If you think the notation you mention is in widespread use, and its addition would be helpful, you could add it to the list of alternative notations, next to $A^{*},A^{H},{\mbox{ or }}A^{\dagger }\,$. But again, the * thing might mean different things to different people. Oleg Alexandrov 01:47, 21 Apr 2005 (UTC)

Ok, the notation may very vell not be in widespread use. I've previously also used the "H" notation (in medical ultrasound). What about including the $A^{H}\equiv {\overline {A}}^{T}$ (or simmilar using the "*" notation) equation, which I find easier ut understand than the current definition? --Fredrik Orderud 09:07, 21 Apr 2005 (UTC)

Sure. But again, putting the notation with the star where star means conjugate, will conflict with the star where star means transpose. The notation with ${\overline {A}}^{T}$ looks fine. Probably it is more appropriate to include it in the list of alternative notations, than to replace everywhere the current notation with this one. What do you think?

• I added the $A^{H}\equiv {\overline {A}}^{T}$ definition since it seemed like that was ok. Dan Granahan 15:09, 19 July 2005 (UTC)
