## Answers to Questions

### What is a complex matrix conjugate? (Definition)

The definition of a **complex conjugate matrix** is simply the matrix of the conjugate elements of the matrix.

For the matrix \( M=[a_{ij}] \), the conjugate matrix is noted with a bar \( \overline{M} \). For a complex value \( z \), you note \( \overline{z} \) its conjugated value. Thus, the general formula is:

$$ \overline{M} = [\overline{a_{ij}}] $$

Remainder : the conjugate value of \( a+ib \) is \( a-ib \) (See the dCode page dedicated to complex conjugates)

### How to calculate the complex conjugate of a matrix?

The conjugate matrix is calculated for a matrix with complex elements by calculating the conjugate value of each element.

Example: $$ M=\begin{bmatrix} 1 & 2-i \\ 3 & 4+2i \end{bmatrix} \Rightarrow \overline{M}= \begin{bmatrix} 1 & 2+i \\ 3 & 4-2i \end{bmatrix} $$

Use the character i to represent \( i \) the imaginary unit for complex numbers.

### What are the properties of a conjugate matrix?

A double conjugated matrix (conjugated two times) is equal to the original matrix. $$ \overline{\overline{M}}=M $$
