According to the first condition, this is a necessary condition, but not a sufficient one. Therefore, the two definitions are not equivalent. Presumably it should also include the fact that the summation should equal
1562:
1489:). Now, perhaps their are alternative definitions of orthogonal and unitary matrices out there, but for internal consistency, the definitions on this page need to match those elsewhere in Knowledge (XXG).
531:
1184:
Actually, no, hang on. That alternative definition is dangerous. Is there anything to prevent these matrices having zero-valued elements? If not, then the alternative definition will be meaningless.

it's saying that each element of the conjugate transpose is the inverse of the corresponding element of the original matrix. This is clearly not the case in the example.

I see someone's now removed the alternative definition from the lead. If that's because it's wrong, it also needs removing from the "Properties" section.

Does the jacket matrix work over fields in general, or only over the specific examples mentioned? If it's the former, all that need be said is:

Maybe I'm being slow, but I'm not sure how that validates the "discrepancy" I think exists above! If I understand the notation:

A possible compromise is to simply remove the definitions. What purpose do they serve on a page about jacket matrices?
