Let U=(13i3−i). What is U†?

Explicitly indicate multiplication with a * symbol. For instance, you should write 3*i+2 instead of 3i+2.

To find the Hermitian conjugate (also known as the adjoint) of a complex matrix or vector, we take the complex conjugate of each element and transpose the result. In this case, we have U=(13i3−i).

To find U†, let's break down the process step by step:

Step 1: Take the complex conjugate of each element in U.
- The complex conjugate of 13i is -13i.
- The complex conjugate of 3 is 3.
- The complex conjugate of -i is i.

So, the complex conjugate of U is (-13i 3 i).

Step 2: Transpose the complex conjugate of U.
- To transpose a matrix or vector, we simply switch its rows and columns.

Transposing (-13i 3 i) gives us the matrix:

(-13i)
(3)
(i)

Therefore, U† = (-13i 3 i).

Note: In the context of the original question, it is not necessary to indicate multiplication with a * symbol as used in algebraic expressions. The use of the * symbol is more relevant for expressions involving multiplication in programming or computer contexts.
