Bereken $$$\frac{\sqrt{2}}{2} \left[\begin{array}{ccc}0 & \sqrt{2} & 0\\1 & 2 & 1\\1 & 0 & 1\end{array}\right]$$$.

Vermenigvuldig elk element van de matrix met het scalaire getal:

$$${\color{DeepPink}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left[\begin{array}{ccc}0 & \sqrt{2} & 0\\1 & 2 & 1\\1 & 0 & 1\end{array}\right] = \left[\begin{array}{ccc}{\color{DeepPink}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(0\right) & {\color{DeepPink}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(\sqrt{2}\right) & {\color{DeepPink}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(0\right)\\{\color{DeepPink}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(1\right) & {\color{DeepPink}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(2\right) & {\color{DeepPink}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(1\right)\\{\color{DeepPink}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(1\right) & {\color{DeepPink}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(0\right) & {\color{DeepPink}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(1\right)\end{array}\right] = \left[\begin{array}{ccc}0 & 1 & 0\\\frac{\sqrt{2}}{2} & \sqrt{2} & \frac{\sqrt{2}}{2}\\\frac{\sqrt{2}}{2} & 0 & \frac{\sqrt{2}}{2}\end{array}\right]$$$
