Write a well$-$structured MATLAB function procedure named fnorm to calculate the Frobenius norm of an $mn$ matrix.

$||A|{|}_f=\sqrt[\phantom{2}]{{\displaystyle \underset{i=1}{\overset{m}{}}}{\displaystyle \underset{j=1}{\overset{n}{}}}{a}_{ij}^2}$

Here is a script that uses the function

$A=\left[\begin{array}{ccccccccc}5& 7& 9\text{;}& 1& 8& 4& 7& 6& 2\end{array}\right]$;

$F_n=Fnor{m}^n(A)$

Here is the first line of the function

function Norm $=F_{\text{n}\text{o}\text{r}\text{m}}(x)$

Develop a MATLAB versions of the function using nested for loops.
