$$$\frac{\sqrt{2}}{4} \left[\begin{array}{ccc}0 & \sqrt{2} & 0\\1 & 2 & 1\\1 & 0 & 1\end{array}\right]$$$

Calcular $$$\frac{\sqrt{2}}{4} \left[\begin{array}{ccc}0 & \sqrt{2} & 0\\1 & 2 & 1\\1 & 0 & 1\end{array}\right]$$$.

Multiplique cada entrada de la matriz por el escalar:

$$${\color{DarkCyan}\left(\frac{\sqrt{2}}{4}\right)}\cdot \left[\begin{array}{ccc}0 & \sqrt{2} & 0\\1 & 2 & 1\\1 & 0 & 1\end{array}\right] = \left[\begin{array}{ccc}{\color{DarkCyan}\left(\frac{\sqrt{2}}{4}\right)}\cdot \left(0\right) & {\color{DarkCyan}\left(\frac{\sqrt{2}}{4}\right)}\cdot \left(\sqrt{2}\right) & {\color{DarkCyan}\left(\frac{\sqrt{2}}{4}\right)}\cdot \left(0\right)\\{\color{DarkCyan}\left(\frac{\sqrt{2}}{4}\right)}\cdot \left(1\right) & {\color{DarkCyan}\left(\frac{\sqrt{2}}{4}\right)}\cdot \left(2\right) & {\color{DarkCyan}\left(\frac{\sqrt{2}}{4}\right)}\cdot \left(1\right)\\{\color{DarkCyan}\left(\frac{\sqrt{2}}{4}\right)}\cdot \left(1\right) & {\color{DarkCyan}\left(\frac{\sqrt{2}}{4}\right)}\cdot \left(0\right) & {\color{DarkCyan}\left(\frac{\sqrt{2}}{4}\right)}\cdot \left(1\right)\end{array}\right] = \left[\begin{array}{ccc}0 & \frac{1}{2} & 0\\\frac{\sqrt{2}}{4} & \frac{\sqrt{2}}{2} & \frac{\sqrt{2}}{4}\\\frac{\sqrt{2}}{4} & 0 & \frac{\sqrt{2}}{4}\end{array}\right]$$$

$$$\frac{\sqrt{2}}{4} \left[\begin{array}{ccc}0 & \sqrt{2} & 0\\1 & 2 & 1\\1 & 0 & 1\end{array}\right] = \left[\begin{array}{ccc}0 & \frac{1}{2} & 0\\\frac{\sqrt{2}}{4} & \frac{\sqrt{2}}{2} & \frac{\sqrt{2}}{4}\\\frac{\sqrt{2}}{4} & 0 & \frac{\sqrt{2}}{4}\end{array}\right]\approx \left[\begin{array}{ccc}0 & 0.5 & 0\\0.353553390593274 & 0.707106781186548 & 0.353553390593274\\0.353553390593274 & 0 & 0.353553390593274\end{array}\right]$$$A
