Conjugate cannot work in an expected manner for X + I Y Z

Posted 2 years ago

This question comes from here. The test code snippet is shown below:

As you can see, the last one didn't work as I expected. Any tip/comment/fix for this behavior is highly appreciated.

Good. It works. Thank you very much for the tip. I also note that the following simple form gives the same result, so it is sufficient:

(I Y Z)\[Conjugate] // ComplexExpand
(X + I Y)\[Conjugate] // ComplexExpand
(X + I Y Z)\[Conjugate] // ComplexExpand

Regards, HZ

Try:

(I Y Z)\[Conjugate] // ComplexExpand[#, _ \[Element] Reals] &
(X + I Y)\[Conjugate] // ComplexExpand[#, _ \[Element] Reals] &
(X + I Y Z)\[Conjugate] // ComplexExpand[#, _ \[Element] Reals] &
