Let:
$$
\mathbf{A}=\left(\begin{array}{cc}
1 & -3 \\
-2 & 5
\end{array}\right) \quad \mathbf{x}=\left(\begin{array}{l}
4 \\
3
\end{array}\right)
$$
Compute $(\mathbf{A} \mathbf{x})^T, \mathbf{x}^T \mathbf{A}^T, \mathbf{x x}^T, \mathbf{x}^T \mathbf{x}$. Is $\mathbf{A}^T \mathbf{x}^T$ defined?
Non riesco a capire come ottenere la T, qual è il passaggio?
