The hermitian of a matrix is defined as the complex conjugate transpose which modifies the matrix by:

  • transposing the matrix
  • conjugating all complex numbers \begin{bmatrix} 1 & 1+2i \\ 1-5i & 9 \end{bmatrix}^H \= \begin{bmatrix} 1 & 1+5i \\ 1-2i & 9 \end{bmatrix} The hermitian of a real matrix has no effect since for any , and therefore
