Transpose of a product of three complex matrices

Formulation 0

Let $A \in \mathbb{C}^{N \times M}$, $B \in \mathbb{C}^{M \times K}$, and $C \in \mathbb{C}^{K \times H}$ each be a D999: Complex matrix.

Then \begin{equation} (A B C)^T = C^T B^T A^T \end{equation}

Proofs

Proof 0

Let $A \in \mathbb{C}^{N \times M}$, $B \in \mathbb{C}^{M \times K}$, and $C \in \mathbb{C}^{K \times H}$ each be a D999: Complex matrix.

This result is a particular case of R4668: Transpose of a finite product of complex matrices. $\square$
