WebApr 1, 2024 · A Hermitian matrixequals its own conjugate transpose: MH=M{\displaystyle M^H = M}. A normal matrixis commutative in multiplicationwith its conjugate transpose: MHM=MMH{\displaystyle M^HM = MM^H}. A unitary matrixhas its inverseequal to its conjugate transpose: MH=M−1{\displaystyle M^H = M^{-1}}. WebSince the transpose matrix is defined for complex matrices, this meaning is kept for the defined operations. In order to write one defined operation for both real and complex matrices, use the conjugate-transpose in all cases. This will result in only real operations when the data arrays are real.
