Aufgabe Berechnung von Matrizen:
Berechnen Sie:
(a) \( \left(\begin{array}{ccc}-4 & 1 & 0 \\ 1 & -1 & 1\end{array}\right)-2\left(\begin{array}{ccc}2 & 0 & 2 \\ 0 & 1 & -1\end{array}\right) \)
(b) \( \left(\begin{array}{ccc}1 & -2 & 4 \\ -2 & 3 & -5\end{array}\right) \cdot\left(\begin{array}{ll}2 & 4 \\ 3 & 6 \\ 1 & 2\end{array}\right) \)
(c) \( \left(\begin{array}{ll}0 & 2 \\ 0 & 3\end{array}\right) \cdot\left(\begin{array}{cc}-2 & 5 \\ 3 & -5\end{array}\right) \)
(d) \( \left(\begin{array}{cc}-2 & 5 \\ 3 & -5\end{array}\right) \cdot\left(\begin{array}{ll}0 & 2 \\ 0 & 3\end{array}\right) \)
